I just bought a 5 spot jewel cichlid today. I introduced it into my 100g growout tank and he and the grammode have been going at it when they see each other. Both are about 4 inches. Can these 2 types of fish live together? I know grammodes can be nasty, but didn't know that 5 spot jewels could be that aggressive. Anybody have both of these fish as adults in the same tank? Which one is more aggressive?
