I used to use a .5 gallon and all he could do is turn 90^ then go about 2 inches then do it again. After joining the forum and despite the fact that i thought that is their primary habitat and that they liked it, i could tell hi didnt. Nothing by this, but i have since got a 2.5 gallon for my new betta (the other died) and its amazing to watch him actually occupy himself, such as brushing the plants, messing around in hes hiding spot, and freaking out for feeding time. I actually put a ping pong ball in the tank and he pushed it around for half a minute then scurried away when he popped it in the air and it made the water shiver. but ANYWAYS.... i dont understand how u dont have room for a bit bigger tank, since its hard to find a spot my 2.5 gallon doesnt fit in, i dont understand why you cant find one.
Miami Ice- a unsocial butterfly who swims away from me everytime i pass his tank.
