well....lets see.....
lets assume we have a BIG reservoir ( 7" X 7" X7" ) so...if we make it out of.....either lexan or acrylic, the we could take a piece of whatever it is and make a kind of wall so that the fish have a place to chill (haha pun intended). now i remember having a bunch of gold fish a long agoand i had some little air bubbler thing, for lack of a better way to describe it, it did exactly what is needed. it put air in the water for the fish. i doubt the temp was at 30 C though.
hmmm....now what kind of fish like it at 30C?
