I have a 2 years old discus pair, started cleaning different sites in the tank and dance to each other all time, they still cleaning a pvc pipe for about 2 month and no sign of eggs, until one day I found one of them hiding from the other, with shredded fins, I separate them for about 5 days, when I
removed the divider they are still fight each other, can you tell me about this problem?
1. Both of them could be males. Males are very fond of dancing.
2. They force each of them to spawn but fail.
3. Then they will fight.
4. Give them a female.
