My Oscar won’t eat!!!

[ygwilliam]

I bought three oscars from my lfs two weeks ago and one of them hardly eats. All of my water parameters are perfect and their in a 100 gallon tank. I bought two albino iscars and one albino tiger Oscar. Their all roughly 2.5” in size and they get fed plenty. My problem is though the albino tiger doesn’t eat like a normal Oscar should. He’ll eat maybe two hikari pellets a day and that’s about it. I do feed them a varied diet of rosy red minniows, chopped up tilapia, hikari cichlids staple pellets, and bloodworms. The albinos eat it all and what they don’t eat the bottom feeders eat. However that albino tiger Oscar doesn’t eat as much as he should. Does anybody know why? Do I need to try to feed him something different?

And when he first got in there he did try to eat a Cory cat I had accidentally left in the tankbut then after a while spit it out. Could he have gotten a cut on the inside of his mouth that is bothering him?

I once bought a tiger Oscar (round the same size as yours, actually my first fish when I just started out in the hobby), who looked great in store, responsive, very healthy, but like yours hardly ate anything. It worried me as Oscars have a reputation of loving to eat.
I carried on feeding everyone else in the tank as per normal (pellets, bloodworms etc), and after a week he still refused to eat.
I tried crickets the one day and he went made for them. I realized he was just a very fussy fish with a discerning palate. and so for the 4 years I had him before I had to move countries I could only feed him crickets (I actually had to start keeping crickets too, which I raised on fish pellets, flake food and veggies to gut load them), along with earth worms or other insects I would find in the garden.
Then he would eat like an O should. Never in the time I had him he took pellets or store bought food. I did eventually get him to start accepting some tilapia/hake/pangasisus pcs after about 2 years, but he never liked them as much as he liked his crickets and insects.

Thanks for the suggestion. Now that I think of it I have seen him eat a moth before so maybe insects are the way to start.
