I just couldn't seem to find a straight answer online. The store I buy my fish as do know what I have in here so I'm hoping they aren't just trying to make money on me and I'm overstocking my tank. So here I am to double check. So, as of today, I have 5 mollies, 2 gourami's, 2 cory's, 4 snails, and 1 African dwarf frog. How am I doing capacity wise?
The mollies, corydoras, and snails are fine.
What kind of gouramis? If they are honey gouramis then you may be ok. If dwarf gourami then I'd be a little concerned with all the other tank inhabitants. But if they are blue or gold gouramis then they will not work in that tank.
As for the frog. I really don't know anything about those so I can't advise there.
I will say corydoras do best in larger school 5 or more. But with your current stocking you might not have room.
Also on the mollies if they are sailfin mollies I believe they get too big for that tank also. But again getting a little out of my experience there.
