I have a .5 gallon tank and I know that's way too small. It's just a small glass fish bowl sitting on top of my dresser. The only problem is the length of the tank. Does anybody have any suggestions as to what kind of tank I should get?
you can get some tanks that are taller instead of wider which may help in your circumstances. Like others said bigger is always better but even a 1gallon is better than a .5 so it all depends on your space restraints and your fish budget.
1.5-2+ would be better. There are small tanks out there that are 3 gallons. I have my betta in a 3 gal kritter keeper, which is not the best but better than what he was in. Look around in wal mart.
I know about the space thing, I put some of my dolls off my shelves to make room for my little buddy.
