I have a pond and started with 5 small goldfish. I thought it might be a good idea because of their size, to bring them in for the winter so I placed them in a 30 gallon.They were 3 different species. 2 shubunkin,2 fantail, the other not sure what kind it is. What I realized after losing 2 is the one type is attacking and inflicting injury to the others trying to prevent them from eating.I give them ample food twice a day. Should I not have them together if they are of different species?
