Im upgrading to a 20g, I don't have the option of going bigger, and I have the new tank cycling now. I have a powder blue cichlid that will be moveing in there, but I dont want him to be all alone. Im trying to figure out what other types of fish will get along ok with him. Yellow Labs were suggested, but then I was told by another that 3 or 4 cichlids would be too much for this tank...and I know I want something to keep the algea in check. So I need help decideing.....anyone? I welcome and value all opinions. (Keeping in mind that I do want to minimize the possibility of babies...my other tank is only a 5 gallon, and I dont have room for even a few more fish, 4 or 5 is going to be my limit)
