I have an 80 gallon tank with about 15 largediscus….About 8 of them are not eating….I also added a few new ones andthey are not eating either. I constantly do water changes and i feed them frozen and live bloodworms…I’ve noticed some of the ones not eating are pooping white stuff….could they have parasites and if so, how do i get rid of them?
1. Are they eating before you introduced the new fish into the tanks?
2. The new fish should be quarantine at least two weeks.
3. The white stuff must be fungus.
4. Add Methylene Blue solution plus salt be should able to get rid of fungus.
