I have had this parrot Cichlid for a few years and in the last few weeks she has developed a large lump on her rear left side. She currently lives in a 75 gallon tank where the PH is 8.4, Ammonia 0.0, Nitrites 0.0, Nitrates 05. I have put her in a epsom salt bath twice and it doesn’t seem to help. Does anyone have any ideas on how to help her?
