So we thought we were doing good by upgrading our 10 gallon to a 20 gallon with our 5 mollies. I was told a 20 gallon would be fine. They have been fine for a few months until now. Constant chasing and nipping. We are most likely going to rehome them all and restock our tank appropriately as one of our fish has gotten hurt because of this. It is going to be really hard because we love them but we can’t get a bigger tank because we aren’t supposed to even have fish in the first place and I don’t want them to be constantly stressed with the little room that they have. My question is what are appropriate fish for a 20 high. I also do not want to raise fry anymore. So wanting mostly either all females or all males. Which I know if I get females I might end up with fry again anyways Do not want to hurt our fish again so any advice is appreciated or the link where I can find the 20 high stocking.
