I am starting to wonder about a certain discus breeder which I am not going to name. I have purchased two fish from him and they don't seem to be right. One is 5 inches and has an aggression problem with no matter what fish or how many are in the tank. He/she has a problem seeing its food the eye sight problem could result in aggression, not sure and hides like my other fish. He has been with the other six fish for quite some time around 4 weeks and is very skittish unlike the others. Makes me wonder. I just bought 2 more discus from another breeder near our home and they are doing great. Any ideas?
