So my black arowana for the last 3-4 months has been eating very poorly. About a month ago he went off food entirely, until I recently bought worms and he loves those, eats tons. The issue started when I sold the peacock bass in my tank, which were the only other inhabitants that aren't bottom dwellers (I have 3 stingrays, rather large). He would not eat the food falling to the bottom, he would wait for it to hit the bottom, and scoop the food off the bottom sideways, causing his eyes to have surface damage, similar to eye cloud, but due to the fact that his eye hits the gravel everytime he goes to get the food.
A week ago, I noticed him not swimming, idling maybe 2-3 inches above the ground, opening and closing his mouth repeatedly. I also notice his fins looking as if they were rotting. I have pictures, but he is really camera shy and it doesn't show very well. It is possible the rays bite them during the night when I don't watch, but i have never once witnessed my rays pick on the aro. He has since resumed swimming, swooped in for some smelt but spit it out.
He has been through a rough time, his upper fins are a bit torn from jumping and hitting the lid and they haven't healed. He lost his silver shine and is more grey. Do you guys have any suggestion as to what is bugging him or what to do? I don't have a way to quarantine, and am very hesitant dosing my 400 gallon tank with medication because of the stingrays and the sump (don't want a ph crash or spike of any sorts). Any advice is appreciated.
