There is rocks on bottom,obviously, ( 2 gallon bowl till i find more room) a big leafy (fake) plant that takes up about a quarter of the tank, but gives enough room to swim between/over/in the plant, and a little shell "cave" that he doesn't seem to use much, though my other one does use his...
He seems fine. I just did a 100% water change (yea i know, not supposed to do that, but i think one of my friends little sisters dropped something in the tank and everything got all slime-y over night) and accidently (! new to the fish business obviously) put him in water a tad to cold. We set him near the heater (not real close, but close enough) and he seemed to bounce back over night... *Whew!* i was worried :-X Thank god.
Not doing that again!
