over the past few weeks or so i noticed this crater in my oscars face hes probably around 6-7yr or so full grown been in this tank since i got him. Since ive noticed it ive been doing increased water changes added additional aquarium salt and started to research what it could be or if he injured himself on a rock in the tank which he occasionally does but never that seriously. My guess is its HITH. His temperment has changes a bit he spends most his time sitting in his corner, he'll come out for a swim every now and then, but sometimes goes in a rampage just thrashing about then goes back to his spot. I also noticed he twitches a bit here and there. Hes been breathing a little heavy, his colors are normal, doesnt want to eat as of the last two days. Last time i saw his feces it was normal, normal color, size, etc. I have been doing large water changes of atleast 75-80% i found my tap water recently has about 40-60ppm nitrates. When i first noticed everything and did a water test nitrates were in the 40-60ppm range. After adding some Nitra-zorb to my chemical filtration they are now in a 10-20ppm range. Ive been dosing with Melafix to help with the open wounds/sores and fight any bacterial infection. I was feeding him Hikari pellets, but recently starting making my own food for him with fruits, vegies, shrimp, some of his pellet food etc to give him a more balanced and vitamin enriched diet.
Tank 90gal 1 Oscar and BN pleco
filtration AC110, Emperor400, and magnum 350 canister
Ammonia:0
nitrites:0
nitrates:10-20ppm
temp 78-80
i think that covers everything, the picture below is from about a week ago the main crater is about the same but smaller lesions have been forming in the area as well.
