so I got a neon tetra and a harlequin Rasbora 3 days ago not knowing that they had to live in large groups of the SAME fish. Right now they are in a 10 gallon tank with 3 snails, 2 emerald Corydoras, and 3 GloFish tetras witch they sometimes school with the GloFish. I have 3 other tanks that are ALL cycled. A 10 gallon with a docile/friendly Betta and a mystery snail, a 10 gallon with a Betta that will attack anything else in the tank including snails, and a 7 gallon with 6 fancy guppy fry. I CANNOT get another tank. I’ve tried taking them back to the pet store and they said no, and i’ve tried rehomeing and nothing. Please help! Any suggestions or opinions are greatly appreciated! I just bought a neon tetra and a Harlequin Rasbora 4 days ago not knowing they needed to school with the SAME BREED of fish. Lol my bad. Anyways right now I have a super overstocked tank it’s a 10 gallon with 3 GloFish tetras, 2 emerald Corydoras, 1 mystery snail, 2 apple nerite snails, and now a neon and a Rasbora. I have another 10 gallon with a docile/friendly male Betta as well as 2 mystery snails (but one hasn’t moved or come out of its shell in days and I don’t know why) I was thinking I could put the Corydoras in there and get 1 maybe 2 more since they do better in larger numbers. But my tank would still be overstocked....right? The Rasbora and the neon do school together all the time and sometimes with the GloFish... so are they good? I don’t want to get rid of any tanks or fish or snails. I also have a 7 gallon guppy fry tank that has 6 guppies in.. maybe I could put the 2 nerite snails in there? I don’t really have the money nor space for another tank lol Any help/opinions are greatly appreciated!
