I have a planted discus tank. Unfortunately the plants are not large as they have only recently planted. I have one dominant discus & he is constantly chasing the other 2 smaller ones.It doesn't seem to intimidate them. They do not huddle in a corner & they manage to get their share of the food. I have noticed some nipped fins, however. I have planted my aquarium heavily with plastic till my real plants take off. What is your opinion on how this will reduce the chasing ?
