Do fish care about what the environment outside the tank they are in looks and sounds like? Do they know they are in a tank?
Fish do have a long term memory of sorts and can remember things if the same thing occurs repeatedly but as Type 7 says i doubt they care what their view is like
I don't know if this applies to other than carp (including goldfish), but they will cease growing when they reach the size that is suitable for the tank. Can't say as I've ever heard of one shrinking to fit a tank that's already too small, though.
Neat information about measuring them, Tommy. I never heard of that before.
Which makes one wonder why there were much, MUCH larger animals roaming about that didn't have this happen.The length of their body was so great that they continually sought out food in swamps and shallow water to support its weight and awkwardness.

If 'bodies of a certain size need water to support them' is a strong evolutionary driver, then how did apatosaurs, seismosaurs and their ilk manage just fine?
