haha, i like it! everyone on here is talkin about there huge tanks, yet you post about one at the opposite end of the spectrum! shows that everyone here can appreciate a nice tank regardless of size
A Betta in there would be far too cruel. I could only think of putting a MTS in there, nothing else. I believe a Betta should have 5 gallons or more at the minimum. ^.^
I use small acrylic containers from local dollar stores, etc. for my tiny setups. And a turkey baster is far and away the absolute best way I've found to change water in these tiny tanks.
Ah, no. They are more functional than pretty. I've only got one running right now. Maybe I'll deck it out with sand and plants and get a few shots someday. Right now I'm breeding a weird European snail species in it, so I'd hate to disturb them.
