Kiera

I have an electric blue acara. He had some ragged fins with white around the edges and a chunk missing out of his tail (no white) I didn’t realize the other acara in the tank reached maturity and started picking on the male. Not sure if it’s fungus, fin rot or just damaged from bullying. The original guy I treated with Maracyn and ich x and he has almost healed. However his friend, was scraping non rocks and swimming with clamped fins.

I was wondering if it was safe to use the liquid Maracyn oxy as part of the trio?
