Oh, I know! Cory Cats! Some of mine breed in my 90 gallon goldfish tank, of the few eggs I was able to save from being scrambled eggs for breakfast, 3 of the babies have survived and are thriving. I love cory cats

What could I breed in a 29 gallon that I could potentially make a little cash from? I am open to anything. THis will not be their permanent home. Meaning, I am only gonna keep this tank up and running for like 6-10 months before I give away the fish and shut the tank down. Right now the tank is a planted tank, so they have to get along with plants. Open to all suggestions. Thank you

Cory cats are way cooler, I've enjoyed them anyway!
