I would do a Salt water and put some seahorses in it. Then some times I would take a good shower without soap and then start swimming and join in there world. You would take great photos and maybe even breed them. even if you only got 10% of the fry out and only 50% of them lived you would still have hundreds of babys a year that live. I mean if you start out with 50-100 Seahorses. Heck you could pay for it just from the fry
I think this is a joke, but what the heck, lets have fun; you should havein this tank (which the author, probably doesn't have) a big amazon discus/angel/cardinal enviroment...
Snappers are solidary animals, and would kill eachother, also if the tank is supposed to be that high, they would die because they would get to tired cos they'd have to swim for air.
