one more question though is these 2 fish are about 6-7 inches male slightly bigger and i only had them in the tank for 2 months or so and its a community tank with 6 other different cichlids. Will they need to have more time to mature at a larger size? male doesn't quite have his hump yet and is there too much distraction with the other fish in the tank for them to mate and spawn? I'm sure if they were not a compatible pair they would have already tried to kill each other?Quite alright mate, biffas are great fish and will look stunning when there settled.
