I learned that last week. I had six, but one got beat up pretty good last week. I tried save him, but all he was doing was suffering. The only part that I didn't understand was that I had thyese discus for about 1 1/2 years. Every one seems to be getting along fine now.Originally posted by Deb2
Certain discus can be very aggressive toward other discus. I have seen groups of discus that have a certain hierarchy and there will be one that gets picked on (low fish on the totem pole). Other groups that are extremely peaceful.
