I've had nothing but good experience breeding GB rams. Provided you acquire heathly stock and treat them well they should get down to breeding once they are mature. The fry are small, so I fed mine rotifers as a first food along with vinegar eels and the smallest strain of newly hatched brine shrimp. I let the parents raise them for the first couple weeks, then would move the two hundred or so babies to a 55. For me, the hardest part is finding healthy rams at local pet shops. Maybe members other members here can help. I don't have rams at this time (moved up to the full size Geo's.)
