Decoder;1376559; said:A male GT will want the 55 only for himself. I think evetually you will have to remove other small cichlids. With a weak cichlid like FM, its not worth taking the risk. Also what is the point of adding a fish if you will remove it in a year?
Good point
Also, I would expect the GT (If its a male) to run the FM around until it destroyed it. MY male GT chases my FM and they're in a 90 with a JD.
I would say that if you've had your current fish (FM, Con) for a while, judge their temperment...How would you expect them to react? I added my Male GT at 4 1/2" cause I knew my JD would be cool with another fish in the tank, the FM is just a bluffer and doesn't nail anybody, so it works well.
I'd try it but make sure the GT is the same size or even a little bigger than the others because they are very slow growers IME, and if it fell too far behind the others it may be double teamed? I think it may end up being the GT's tank after he hits 5-6"
Good luck
