So my green terror has been is a spiral downward for few days now maby a week. I don't understand what's wrong with him. He was recently living perfectly fine with 2 blood parrots. They both unfortunately died unexpectedly one morning. Along with my peacock eal. He seemed lonely and didnt move much I thought he was just lonely since all his friends were gone.( ik ima child) pet smart reccomended I buy anouther green terror so I did and he didnt like that he actully ruped the new one fin so that got returned. But sonce then hasnt been the same. He recently started laying on his side. He didnt move for 2 days. Hasnt eaten. He was a typical gt won't eat anything off the ground but now its nothing at all!! I very worried now a little more. He now has badly dammaged side fins. He look like a fish out of water on the bottom of the tank. Its weird I tryed melafix to repair his fins but he started going crazy and I noticed some salt like things on him so he is going throuhh super ick cure rn. Help me please I don't under stand what's wrong he just flops around.
