I have a 55 gallon open right now along with a 30 gallon. In the 30 gallon growout i have a yellow lab and some other mixed africans but I'm looking to see if i can identify them to make sure they aren't hybrids. The other fish i can identify is a bumblebee cichlid. What else could i add to the 30 and then to the 55. Forgot that i have then 150 for the future setup. All fish are about and inch or so. I'm keeping ph between 7.5 and 8.
