I have a female black molly who has repeatedly exhibited what looks like patches of fungus. She is treated and recovers in a 5gal hospital tank only to have her symptoms reappear a few days after returning to the main tank. The main 84gal heavily planted community tank has Neon Tetras, Congo Tetras, Australian Rainbows, Otos, Siamese Algae Eaters, Blue Gouramis and a Dwarf Gourami and Zebra Danios. I guess I need to treat the main tank. I was planning to use either Maracyn 2 or Pimafix. Will either of those hurt the plants? Please help.
