Hi, great little tank! Oto's aren't a good idea. you don't have a big enough tank to properly support them. I'd stick with the betta and snail for stock.
I'm just curious... aren't you worried about your betta jumping out? I had a betta in my dorm room (eoooooons ago, lol) and there was no lid and he jumped out in the middle of the night and went to fishy heaven. Would hate to see your little guy meet the same fate.
We have no limits. As long as they are not predatory we can have whatever we want![]()
...it's an antique Meta-frame and much heavier than the Pico. It's sitting right next to my 6 gallon.
Ohhh! Pictures????
I really like your tank that you have and as others have said, I think it would be really neat on a desk with a CPO crayfish in it.:
