Fish are smarter than us

Ever wonder why you could never catch a fish by chasing it with a net?

Why? because where fish live the only color you can see is blue. If you decend down in the ocean about 40' everything becomes blue because blue is the only color of the srectrum that gets through that much water. (It is either 30' 40' or something like that, I am a diver but I never take a rueller with me and I forgot the depth that colors disappear, work with me)
So all fish appear blue in the sea.

I have caught a LOT of fish with a hand net, slurp guns, etc... they are pretty dumb, some are less dumb than others. The only fish that is not that dumb are Yellowtail Snapper and from time to time they do let the guard down and end up in my stringer.
If everything looked blue down there it would be impossible for me to ID a fish before I pull the trigger. Most snappers look grey in color, but as soon as I get to the surface they look orange/red; Ex. Dog Snapper, Grey Snapper. By the way, I can see a Glasseye Snapper from a long distance, that red color is unmistakable.

The only thing a fish cares about is food, and not getting predated.
 
Everybody knows reef fish prefer hard liquor!

My firefish prefer Grand Marnier bottles.


But some of my fish prefer beer bottles.


Hermit crabs prefer antique bottles.



And some will drink anything.

You must have a better lateral line than them. I have also caught a lot of fish, but they know exactly where the net is.
As for thwe blue, if you go down about 60', virtually everything is blue no matter what color it is near the surface. And if you go 100' everything is a darker blue, even if it is a long nose butterfly. Color does not penetrate very far in the sea. as the pictures show at the start of this thread.

I have also been diving since the late 60s. Maybe the water is different now. :nerd:

 
PaulB...Thank you for this read, im glad I found it on accident! Is anyone against a tank that has a Live Trash Aquascape in place of Live Rock? I have a stack of Glass and Plastic I have yet to take out haha. If I can just set up a tank with it I would not have to make the long trip around my house :frusty:
 
Throw it in there:der:
 
My favorite 300 gallon fresh water tank had an entire toilet bowl in it with all the associated plumbing. It was in a large NYC LFS
 
Umm...there's a whole toilet down the alley...imagine a Carlson surge device made from his inspiration!? I could install the toilet In my upstairs closet. Feeding would be fun...just "drop a load" (of food) in the bowl and flush hahaha. Someone tell me not to do that please haha
 
I'm extremely wary of those quick to spout their credentials and experience as a way to legitimize what ever advice their spouting... claiming their way is the best and you're ignorant and inexperienced to see it differently.
A big problem with taking advice on line is that anyone with any, or no experience can give advice. The vast majority of advice is given by people with only a few years of experience. If you want to give advice on a particular animal. I feel you should have had at least a few of them and kept them for a number of years. So many people buy a Moorish Idol and say something like "I bought it because it was eating anything so I think it should live forever" No, it won't. They all eat. I have had many of them for many years starting in the 70s and I never had one that didn't eat. The same with mandarins, which I have also been keeping since the 70s, I find them the easiest, least maintenance fish there is, but not in a 10 gallon tank and not by feeding them frozen food. Keeping these, or any fish for five or six years is a failure (unless it is a seahorse, pipefish or small gobies with short lifespans)Most of the fish we keep live normally at least ten years and fish like clowns live over 20 years so If you keep one for a year or two, that is not enough time to form much of an opinion about that particular fish. The majority of posts are about diseases, but diseases should not be an issue except in the newest of tanks. Fish that are fed correctly almost never get sick but very few IMO feed correctly. I am not going to get into that because I have posted my thoughts on that many times. :wave:
