I've seen rams at just over 3 inches, a friend used to breed them. He fed them lots of blood worms,flake, frozen brine shrimp, don't know about beef heart but he also had lots of discus so i wouldn't doubt it. He had a system that changed 10% of the water daily, sa well as a 50% change once per week. ============ Reminder: Kindly quote parsimoniously when replying ============= This is the apistogramma mailing list, apisto@aquaria.net.
