"So Tang police (I know you will be all over this like stink on a two week old dead flounder) if someone wants to put "their" own fish, that "They" bought with "their" own money. It is "their" fish and can do with it what they want. I eat fish almost every day."

:D LOVE IT, in your face 'Tang Police'!!
Thank you @Paul B for this piece of info.
PS: I don't keep Tangs.
 
This is a great post by @PaulB. I have often felt when I see a fish that is sickly in a LFS, I should purchase it and try to save it and give some quality of life. That is the story of our Hippo in my previous post. It survived hypo salinity treatment for ich at a very young age.

Genesis 1:26-28

26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.

With that comes great responsibility, and sound desicions should be made as not to abuse it.
 
I have found that same thing with hippo's, they definitely grow to the tank size. I can't say that about all tangs because I have not had every one. I also don't keep them any more as I just find them boreing, but that's just me.

Genesis, 1:827-42
Thou should not listenth to every, little thing thou read as the tangith police will sometimes Quothith something in which they heardith a rumor and yell ath you.
 
Get post PaulB. And I have seen where most fish I have taken care of only grow to the size of the tank and have all been very healthy too.

Cheers,
Alex
 
I am glad this thread spurred some discussion and not the normal threads such as: "I have a 20 gallon tank help me pick out fish, I want red ones". Or I just bought a mandarin and he won't eat flakes, what should I do?

Right there with you, I actually don't come on here as much as I use to. Tired of seeing the same threads over and over.
 
Let's mix this up a bit more, if tank size doesn't limit grow on most fish then where do we draw the line? Can we put a trigger in a 40gal? If the fish eats, grows and spawns then it shouldn't be a problem right? What about how much room a fish needs to swim? I was at my grandparents retirement home and in the lobby was a 60 gallon with a emperor angel in it along with 2 wrasse and 2 other angel. The Emperor was healthy, fat but had no room to turn around in the tank.

Personally, I draw the line with my conscious. Any responsible aquarist is not going to put a fish in their system that is going to blantently out grow an aquarium in a short time span.
Eventually, I know I will have to remove my Hippo and Sailfin from my aquarium. I have hopes to enjoy them fir several more years . I've already got my eye on a 225.
I think the subject that upsets me the most is that LFS owner who allows his employees to sell a fish to anyone, no matter what species it is without questioning the buyer about the size of the aquarium or the compatibility of its potential future tank mates.
As for the Emperor in the 60, someone needs to be approached that is in charge of its care and alternatives should be proposed for a plan of action to improve its quality of life.
 
Sapper, thanks for your reply. We as "responsible" aquarists try to keep, and keep as safe and "happy" as we can, our fish. But for every fish we get, hundreds or thousands die before they even get to a store. So we are not quite that responsible in the first place. Then many die in the store before we even see them. I realize that we try as hard as we can (most of the time) to keep these guys healthy for a few reasons. We are, as I said "responsible" and they cost money. But there are a lot of variables here as to what we consider proper care. "I" personally feel that if you quarantine a fish for 72 days you are being irresponsible and dooming that fish to a life of potential disease. I know that is a bold statement but it is how I run my tank. I keep my fish immune so they never get sick and almost always die of old age. Does that make me irresponsible? My fish are all old and all spawning and never get sick. I am talking decades, not years.
Sometimes I put tangs in smaller tanks than what is recommended by someone who calls themselves an "expert". They too die of old age and "never" get ich. I keep copperband butterflies and don't find them difficult at all even though my tank is only 100 gallons and that fish could get to about 9" in the sea. Am I irresponsible? I feel people are not caring for their fish if they allow them to get sick. Fish should "never" get sick. I feel that if you feed fish correctly and get them into breeding condition, you are doing the right thing and anything else if cruel. Does that make me a bad person? I feel that if you have paired fish and they are not spawning, you are not feeding them or caring for them correctly. I wish no ill will on anyone who has fish that are sick or not dying of old age. They hopefully will learn eventually. This hobby is run on rumors and most of them are laughable. HaHa, I am laughing now. Many people still feel that quarantining and treating fish after they get sick is the way to go. Most people actually feel that way. Just search for how many people lost all their fish from a disease after they quarantined. I am by far "not" an expert or the God of fish, but I have been doing this probably longer than anyone else so I have a few theories. I am one of the very few people who came about these theories on my own by spending time with the fish way before computers were invented and none of my theories come from rumors started by a researcher 40 years ago who probably never dove and kept a tank for a few weeks just to count the days that an ich parasite lives. Then we take that information and apply it to our tanks (which are not in a lab) and use that information as if it is the only way to go.
I have found, through many, many years of trial and error a way to keep fish healthy and spawning even if they are not living in the largest tank I can afford. Tank size is one aspect of fish keeping, but not the only one. If you keep a lipstick tang in a 500 gallon tank and then feed it flakes, is that responsible?
I feed my fish live foods every day, which is why they are spawning, but very few people do that, and then we have thousands of disease threads. I have never been on one, I think I know why.
It took many years but I have learned how to keep fish disease free and hopefully "happy". How do I know they are happy? They are happy because they are spawning and dying of old age. When I am "spawning" I am happy and if I die of old age, That will also make me "happy. Depending on who my care giver is near the end. :rolleyes:
These points are why I wrote a book. On this and other forums thousands of people are now shaking their heads and saying "The Old Geezer lost it". Maybe I have, but my spawning 25 year old fireclowns are even now reading this over my shoulder and laughing. It is hard for them to laugh and spawn at the same time. :)
Of course my theories are not the only theories. Thousands of people get it and can also keep their fish for many years. There are many ways to do this but most of it is common sense.

As for LFSs. They are a business and not a very good business which is why so many fail. Their customers, like customers of almost all businesses should know that the LFS is there to make money. That is their first requirement. If they don't do that, they won't be there to long. We as responsible fish custodians need to research the creature we want to buy before we go into a LFS to see if we are able and willing to take care of it. How many posts read: I bought a mandarin and it doesn't eat flakes, what should I do? That guy in the LFS who makes minimum wage is more interested in texting his girlfriend than telling you not to put a tang in a five gallon tank. :eek:

I would never say you are irresponsible. To me, people such as yourself are the hobbyists best tool out there for making good decisions.
You time, advice, and experience are your stock in trade and it is appreciated by myself that you are willing to share so much.
There are just many fish I would love to keep and I always think twice and usually talk myself out if it based on what I know I can support.
This clown is 12 years old this year. Lives in a 40 gallon breeder.
It about 4 inches. It has never spawned since it would rather bully a potential mate from the get go.

There are some forums I can't post this thread or it would be closed as fast as I posted it. I would also get nasty letters and I am too old for that nonsense. If you have a valid opinion that is not re-hashed rumor, I would like to hear it. I get that all the time from my "nitrate factory" reverse undergravel filter. Those negative comments are always from someone who never used the thing. :cool:
Your clown is a perfect example of a healthy fish in a very small tank. In the sea that fish gets much larger. I have seen many of them and they get huge. If he were put into a larger tank, he would grow larger. I know they can be bullies as all clownfish are. I can't put another clown in my tank either and my 25 year old fireclown is smaller than yours. I don't know how big fireclowns get as I never saw one in the sea.
Here he is spawning last week. Seems happy to me.


There are fish I am also not willing or able to keep so I don't have them any more. But I did have most of them a few times before I realized I can't do it unless I want to start a different tank as not all tanks can support all fish. I love orange spotted filefish and twin spot gobies. But they won't survive in my reef.
 
Caity, thanks for responding. I like the analogy of living in my room. But by the same token any fish in any tank would not feel to good at all because it's normal home is in the sea. If I can keep a clownfish for 25 years in a tank, and it spawns for all those years, I assume it is healthy even though it is only a fraction of it's normal size in the sea.
I also agree with your assessment of people keeping a fish for a few years and feeling great that they did that. I have been saying for years that if your fish is dying for any reason besides old age, you failed. The majority of small fish we normally keep should live about 15 years. Some fish like clowns live almost 30 years and as you said goldfish can live 15. Their relatives, carp can live 60 years.
The tangs I normally kept lived about 12 years but I think they can live closer to 20. I have kept mandarins for 10 years and hermit crabs for 12.
I also feel that we failed if we have paired fish and they are not spawning. Fish that will spawn in a tank, not tangs or other egg scatters.
If we add the fish when they are very young, I don't think the tank size would mean much to them. Some, not all fish as the fish I mentioned in the first post will out grow the tank in no time.
I don't think we can equate fish feelings with ours as I think we are giving them to much credit. I don't "think" fish get depressed as we do. I know they can sulk, fast, and jump out, but I don't feel they think to much into things. Just my opinion of course as I am not the God of fish feelings or anything else.
What you said about fish never being happy because they aren't in the sea. Aren't most fish captive bred these days? So how would they know what it's like in the sea? IMO as far as they're concerned it's perfectly natural to live in a tank with a regular food source as well as almost perfect water condition which I think we all strive for. So as long as they're healthy wouldn't they be "healthy"/ not stressed. I'm not exactly an expert but that's what I think.
 
Paul, I've been throwing eggs at you for years. Unfortunately, my arm isn't very good and the eggs keep falling short. My poor neighbour thinks that I'm throwing eggs at him and he doesn't believe me when I tell him that I'm throwing them at some schmuck on Long Island :)
 
Early on I noticed my clown wasn't growing like I thought he should. He is a tomato so sticking at 2 in a 55 seemed weird to me. Well I upgraded to a 120 and everything else was growing fine except him. Keeping this short, in a newbie mistake I introduced flukes to the tank so I treated everything. Turns out the clown was hosting a tapeworm and that impacted growth. Once he was rid of the worm he began growing again but it is very slow as I think he missed out on that crucial period of rapid growth fish go through. So to sum this up, unless we get a fish as a very young juvenile there may have been past factors that we can't account for when looking at max growth vs tank size. My clown is now in 220 gallons but will likely not get over 4 in at max. That is hoping for plenty more years of growth.

No. Most fish are wild caught. Only some bangai cardinals, some clowns and one or two more are captive bred. The vast majority are wild caught. Tangs, triggers, lionfish, eels, bleenies, wrasses and just about everything else are caught in the sea. Also "no one" feeds fish what they eat in the sea. A large part of the diet for almost all fish in the sea is smaller fish. The reef is full of fish fry and everything eats them. We as aquarists rarely can get this food. Tangs in the sea eat, among other things, fresh algae. Not dried nori as drying anything destroys much of it's nutrition. Tangs also eat all the tiny creatures that is hanging on to that fresh algae. Copperbands and long nose butterflies eat mostly salt water worms that they find in crevices which is the reason for the snout. Moorish Idols live on sponges as I have spent quite a bit of time with them and most of the fish I mentioned in the sea.
I realize commercial companies sell frozen foods from the sea that is supposed to have everything in it that fish need, but it is not the same diet as the fish gets in the sea where the fish can choose exactly what it wants to eat.
The "almost perfect" water conditions we have in our tanks is vastly different than real seawater. Real seawater contains every mineral on earth while ASW contains maybe 90 elements. Not even close.
Sea water also contains chemicals exuded by algae, volcanoes', under sea vents and corals. ASW does not have any of this. Our tanks are artificially lit by either LEDs. Fluorescents or something else. The sun emits all the colors of the spectrum in the proper proportions, K ratings and duration that fish evolved to live in. The moon also has a huge effect on fish as some of them spawn by the phases of the moon. The currents in the sea are totally different than in a tank and vary through the year. Fish also know quite well that they are in only 20" inches of water and fish never live in such shallow water unless very young. Fish also have a lateral line that lets them know exactly what is next to them, under than and behind them. They can sense the glass in a tank, but they can't see it which I am sure drives them nuts. Fish in the sea are also in close contact with parasites, bacteria and viruses. These things that many of us call pests are actually needed by the fish to keep it's immune system functioning which is why I don't believe in quarantine and the "lack" of these things in a tank is the reason for all the disease threads.
Notice all the "dots" in this picture from the Caribbean? Those are fish fry and are everywhere. Almost all fish eat these in various sizes. Fish fry contain fish oil. About a quarter of the fry are liver and that is filled with fresh oil. Does anyone feed these?
Also fish spawn constantly so if you have a male and female of almost anything, and they are not spawning, They are not "happy and far from healthy.

 
Naiad, your tomato clown will probably get larger than that in a 220.
Rybren, I have been making poached eggs out of them. Thanks. :cool:
 
Back in the 90's i had a tang in my 75g (won't say what kind because I hate cleaning up eggs) that lived for 10 or so years till I had a power outage.
After it died I replaced it with the same type ( this was around 2003 and nobody raised an eyebrow about keeping most tangs in a 75... I was not on forums then so it was between me and the LFS).
Anyway, I still have the 2nd tang after almost 14 years and both of the them grew to the same adult size, that is much smaller then in the wild, so am going with tank size influences fish size. I actually considered re-homing my tang to a bigger tank, but since he usually stays within a few inches of whoever is next to the tank begging for food, and the fact my kids would disown me, we are in it for the long haul.
 
Mike, the tang police don't want to hear that. They only want to hear re-hashed information from the 80s. They also think it is cruel. But for some reason it's not cruel to catch these fish out of the sea and put them in a fish tank. That seems to be fine. I am sure your tang would not have lived for 14 years in the sea. I think it is cruel if your fish are not dying of old age. 14 years is a good run for a tang.
You know whats cruel? I went to vote today in the New York primaries and when I went to the normal polling place, it was closed. So I called my town to ask where the voting place was. A woman got on the phone who barely spoke English and told me she didn't know where I should vote. This was the number you call for town information. So I went to my Village office and they said you vote right here. I said, How am I supposed to know that? She said, there is a sign on the pole out by the street. I went and looked. 100 yards away on a light pole there was this 8"X8" paper sign that said "No Parking, Polling place".
I think that's cruel. :eek:
 
In my state they voted in a person as mayor, that was sent to prison for crimes he committed the last time he was mayor of the same town.
Personally I think he was over qualified.
 
Paul awesome thread. And your theory and answer is 100% accurate, " depends on the fish". The last fish I introduced to the tank was 10 years ago, some fish grew, others remain the same. Same environment, so it really depends on the fish!
 
Yes it does. The Tang Police don't want to hear that. :rolleyes:
