hole in my red Oscars dorsal

It looks like something has eaten a round spot out of his dorsal fin creating a separation. There is also a Albino red but they get along great and the Albino is a little smaller so I doubt he is being attacked. I'm wondering if this is some sort of fungus or disease? Please help?

Look's like damage from netting the fish,or possibly somethnig in the way of decor that the fish has perhap's got caught on.
Would maintain water quality with weekly 50 % water changes, and feed variety of quality food's for cichlid's (NO feeder fish).
Hikari pellet food,New life spectrum,bit's of Earthworm's,Krill, cricket's would be welcomed by the fish.
Would lay off food's like bloodworm's which have near zero nutritional value.
Water parameter's must read zero for ammonia and nitrites all day,every day,and nitrAtes (with an A) should be kept under 40ppm with 20 ppm being ideal albeit difficult as these fish grow to approx ten inches inside a year.
Filtration should be vigorous,and tank of at least 90 gal for two grown Adult's.(larger would be better)

The most important medication in your fish medicine cabinet is.. Clean water.

Thank you

I am new to fish keeping but I have been meticulous about my water conditions and filtration. Thank you for the feeding advice. I have been feeding cichlid grow flakes with the occasional blood worms and feeder guppies. Along with your advice I have also found out that feeder guppies can transfer disease and have stopped. My tank size is only 10 gal but I am in the process of starting a much bigger tank. My fish only 2" at the moment and will soon have much room to grow.

also in the third picture you can see a spot above his dorsal where it looks like scales have been rubbed off. Is this of any concern?

sorry to hear hes having trouble, i dont see any whiteish slime type stuff on the fins to indicate fin rot so your good there. im with 1077 with the w/c's and the diet. i would try something with some spirilina its good fiber and nutritional for the fish. dont feed any beef heart or any warmblooded meat. the fat is not compatable with how fish bodies work (this includes no beefheart). if you really wanted to be on the safe side look for melafix its a API product to help with bacterial issues and helps heal fins and is very very gental made from tea tree

Yes feeder fish are bad new's for reason's you have discovered and also due to high concentration of Thiaminase which rob's the fish of needed vitamin's.
Healthy Oscar's grow at a rate of approx one inch a month, and am pleased you are setting up a larger tank.Will be but a couple month's before the Oscar's produce more waste than the filtration on ten gal tank can process due to waste output by the fish, and food's offered in very small volume of water.
Larger tank ,larger volume of water mean's water quality is easier to maintain.
