Three tangs in an IM 40 Fusion

[mauriceaa]

You likely had ich due to overcrowding related stress. The wrasses will still likely fight as they age.

Almost any fish when small is peaceful. These fish have long life spans... 10 years probably for the wrasse and 20-30 for Tangs.

I would consider any catalina goby in a tropical tank an exception with many living shorter life spans. This is the reason you can not find them in many home tanks. It is not that people dont buy or try them... they just only last around 2-3 years on average when not under ideal temps.

Surviving is not thriving.

You had several fish die... some would consider that a failure if the death was anything but old age.

I'm almost speechless. Did you get any advice from the LFS that sold you these fish or did you buy on-line? In the 3 years you have had this tank running, have you done any research on fish compatibility, tank size requirements/recommendations? I'm with other posters that this is a recipe for disaster, certainly in the long term. Are you able to upgrade to a much larger tank soon or rehome some of your fish? Something you might want to consider.

Thank you, For sure it was the stress of a similar specimen the cause the flair-up luckily this has passed for know helpfully forever, I know wishful thinking!

Can we get a pic of the tank?

Sure no worries

It's a 24" tank, of course the tangs follow eachother around. They can all swim in opposite directions and still follow eachother.

Define "not premature deaths" with Catalina gobies. How long did yours live?

I feel like we are being trolled. Do you have a BSJ and shark egg in the sump?

Sorry, the yellow tang is being shy and hiding behind rocks will post during a feeding.

Why do you say that? I'm being honest and as informative as possible thinking I would get good feedback. I never had any thought of hurting any animals in my tanks. The Catalina's were in my 225 for maybe 4 to 5 years, give or take, and do not know of the life span since I got separated and needed to move to a much smaller place? Sold/gave away my tank and livestock. Have had several tanks since and think for the most part pretty successful with them. including my 15 gals in my office, I have known many reefers and fish-only keepers and ALL have had multiple failers with livestock with huge and small tanks. Most with more knowledge than myself in fish/livestock keeping, they all have helped me with giving advice. The IM fusion 40 is an all-in-one setup. No sump trolling, thanks!

Just use some critical thinking... watch these fish in the wild and look at the size of adults. The answer should become clear regardless of what you are seeing now.

Is that not true for all aquariums, no one can reproduce the ocean (size) environment at home, not in a 100 or thousand gals tank. I get what is being said. Look at your setup and tell me they would be happier in your tank or the ocean!

 

[Krully]

I've owned an IM 40. I couldn't even imagine subjecting one tang to living in that cube, but 3? I have no words.

 

[mauriceaa]

I have a nuvo 40 as well and I don't think three tangs would be well. I have a 1.5" baby yellow eye kole and I think my tank is not enough. Also, as people mentioned these fish are territorial. With three tangs, you might as well set up a pay per view for the (tang) MMA fight. You may be able to get away with one bristletooth tang but that's about it.

understood, but so fare not the case. Yes, this may change and I will address this if and when it occurs. I don't want unhappy fish.

Ok but surely a 40g cube is different then a 180g tank.

That argument is one people use and it is a very weak one. At that point you could say you can keep them in a goldfish bowl because nothing is the ocean anyways.

Tangs can live their full life span in something like a 125 or even a 75 for smaller tangs. I don’t think we will find a tang dying of old age at 30 years in a nano cube let alone 3.

A sailfin tang can grow very fast in the right environment with the right amount of space and food. The same sailfin will grow slow in a small nano. It will look and behave fine but I would not consider this healthy or ideal.

Waiting until there is a problem is the wrong idea... fix it before it becomes a problem is how people should operate.

Asking for opinions and then coming up with reasons that what your doing is okay is how every one of these threads goes... I would be really surprised if someone said.. “oh dang I didn’t know! I will start working on a bigger tank or rehome the fish”.

Tbh honest guys I don't see a problem here.
Most of these tangs have a recommended size of 120 gallons. There a 1/3 the size of full grown........... ill do the math...... 120÷3=40 they have an adequate tank for now. And I'm sure the owner takes good care of them..... cough cough you know what I'm sayin. Have a good day mate enjoy your fish! I'm not one to argue.

This WILL change and probably sooner than later either get a bigger tank or think of rehoming in a couple of months.

Video doesn’t work for me lol only annoying part would be getting the tangs out once they get too big , they are super fast it took me forever to get a yellow tang out of a 40b

More power to yah. I'm checking out of this madness. I've got a YT and a Tomini in a 90g and feel like I'm living on the edge some days.

 

[mauriceaa]

So what's your point, you have a better setup because it's bigger, what are you keeping and what is the requirement for what you have? How much given space does each animal in your setup require in its natural environment. So mine is a fishbowl and your is a what?? A bigger fishbowl. Your argument holds no water pon intended!!!

I understand and have done removals before, yes it is a pain in the butt. but doable.

 

[Steph72]

With regards to the tangs, You will need to rehome these guys or upgrade your tank sooner rather than later since they grow pretty fast. They tend to get more aggressive as they grow and need room to swim. I don’t know much about the catalinas so can’t advise on that.

 

[Tamberav]

The point is a certain size tank can house certain fish and they will be able to behave naturally and live a full life span and grow at appropriate rates.

Happiness is anthropomorphism.

It’s certainly possible a fish is healthier in a captive situation free of predators and unlimited food then the ocean. I don’t follow that the ocean is always but do believe fish have certain requirements to keep them alive for a natural life span.

LFS can actually house numerous fish in small tanks without fighting but some theory’s is this is because the fish are under stress and without territory of their own to claim and their lack of fighting is actually abnormal behavior.

 

[mauriceaa]

The whole point of my post was to gain a little knowledge and get better at keeping livestock. Yes, it is not an ideal setup with these fish, (got it) and when they begin to fight (if) or when I see that they are oversized for the tank I will address that when it comes. at this point, it is not an issue, really just looking for I guess a time frame when this may occur. And yes maybe I will upgrade to a larger tank, I'll see. For now, in my ignorant experience, they seem happy and are not having any of the visual issues/signs that I'm hearing about (for now), again I will remove the fish when this happens.

Like I said.. the fish may grow slower when kept in a small tank. I had this discussion with another poster, we had the same Tang, both bought as just a baby. His hardly grew at all in his nano and mine doubled in months in a 80g.

When I had the baby tang in a 25g for observation it didn’t really grow at all. It only started to grow quickly when it became established and settled in the 80g. My guess is stress somehow kept it from growing much.

So waiting and see method may not be the ideal approach but certainly the easiest one.
