It is General Hardness, I want a pair and want to try and breed them. I have been looking for breeders in my area but had no luck. If i cant find a pair is it ok to keep one with other fish that share the same water parameters, Such as rams and cardinals. I have heard it is not good to keep a discus by itself, is this true. Would I have to keep the tank bare because I already baught the stuff for in the tank and I really dont like the look of a bare tank unless I did it just for the youth of the fish.
