Okay guys, I've had this oscar in a dedicated home to him for almost 5 years now. He is grown from a baby and only sharing his habitat with 2 silver dollar fish, also who have been in the tank this same period of time.

I feed him about 6 to 10 large sized hikari pellets around 5 times a week, and do 20-30% water changes once a week. He has two Emp400 HOB filters and an Ehiem canister filter. All his water parameters are clean. No amonia, no nitrites, very low nitrates (keeping an oscar tank with 0 would be nice, but i havent been able to do so).

Over the past month or so, I've noticed he was geting irreguarly larger.. I first thought overfeeding? But I'm already so careful... none the less, I cut his feeding back to 3 to 4 times a week, but the bloatedness did not go away. Then I thought maybe it was constipation? No idea... here are some photos to illustrate what I am talking about..

Any help with what this may be would be greatly appreciated. I don't want to lose this guy. He still actively begs for food and does his general oscar-activities, which as you may know is mainly being lazy or eating.

If it is infact a tumor growing, is it fatal or merely cosmetic? Do any vets do surgeries on fish as small as Oscars? Is it even feasibly worth the cost?
 
Is he pooping regularly?? i notice fish pooping during or a bit after they are fed. If he isnt pooping regularly wait feeding him for a day or two to see if he can releave it. not feeding him for two days will not harm him at all. You can also add slight bit of epsom salt to the tank to help him pass it.


(is that bamboo in the tank?) Bamboo is almost like a bog plant. It will eventually rot underwater. might wanna take it out or find a way for part of it to stick out
 
Unfortunately this has been going on for weeks. I havent noticed him poop much but I also havent been looking that closley. I have already tried a few periods of 2-3 days with out food, BUT I will try it again.

What is the appropriate amount of Epsom salt to treat a 75 gallon tank that houses this size full grown oscar, and for how long?


I will ditch the bamboo.
 
I see HITH i think
 
What about feeding it peas? That would help with the bloat, as long as he is still eating feed him some peas my oscar loves them!!
Good luck>>>>>>!!!
 
Agreeing with everyone else. Epsom salt and Peas. Once he passes this, I would start feeding him peas regularly at least 2 times a week to avoid this in the future.
