At what size do they atart to breed? I bought a male and female 2 days ango and there both about 2''. And im going to say that i got them from a Walmart...yes a walmart! But this walmart is the best one ever cause there tanks were way clean, NO dead fish, and the lady that was getting my rams actually knew stuff about fish and the only fish that they had that would out grow there tanks were Oscars and Pacus, but the lady told me that she is going to take them to a lfs and get something to replace there tanks.
