So what would happen to my fish...

Actually, it turns out that people have studied the balance between gravity and light for fish posture. For many species the fish use both and take an average if they don't match. In one of my favorite experiments, they put a small batch of penguin tetras in a giant centrifuge to alter the gravitational pull and saw them shift their tail positions as the apparent gravity increased.

On the other hand Daphnia only use light as a cue, and will swim to the bottom if you put the light down there. If the water circulates poorly and the lower layers are hypoxic, you can actually kill them. "That," as my ethology prof pointed out with his German accent "is very naughty."

But on a side note - and for future generations...
If you could set-up an aquarium on Mars, would the fish turn a reddish orange color? :idea2:

Actually i've just finished reading this paper about mars. apparently the dust there is so fine that there is no keeping it out without having a completely sealed bubble. any seals meant to open would allow it to seep through. in fact it will go through the fabric of most space suits and through the skin and into the blood. the kidney will probably filter it out but there will be a certain percentage of mars dust that will flow around a martian human, animals , and plants circulartory system with as of yet unknown affect.

So your question has merit. it would be quite possible they would turn reddish orange.

You don't know how much I appreciate your findings!

There are not many here that would delve into such hypothesis' ..! :D
