I know there's not a lot of choice, but just to make this clear, this is a 8"dix12" vase. 8" across and 12" tall. I've tried shrimp in this bowl before, and while I like shrimp, they aren't my favorite for this tank. It's a white-ish substrate with a lot of red/bronze plants, red shrimp just... disappear in there haha.
I actually thought about sparkling gouramis, but the only ones I can find locally get about 3-4" (giant sparkling gouramis). For now, I think I'll keep my Het. Formosa population restricted to my 5, if they're going to overpopulate, I'd rather they do that there, lol.
So that pretty much leaves betta or badis. Guess I'll just go with a betta then, since I can get those local for decently cheap. Thanks for the reality check guys.
