I have a 2 inch ebjd in my 29 as a grow out. I would like to move him to a 40 breeder but since he is small I am worried about moving him since he is so small and costs $20. I have a 4-5 inch electric blue acara in that tank as well as a 5-6 inch firemouth cichlid. It also has a 3 inch polar convict which can be aggressive bc it is breeding. Should I move him to this tank or wait till he is about 3 inches? I know they grow extremely slow so I know this would take a while. I want to add another fish to my 29 and he is going at it with a kribensis and one of my electric blue acara fry that I’m growing out. I know they are sensitive so I would drip acclimated but if you were me should I move him or let him gain some size?
