Remember,
Feeders are treats only
So having an oscar to eat other fishes isn't a good choice for population control
I give Draegan an assortment of foods. Like us Oscars get bored with being fed the same things day in and out. When he was small i would feed him "mini" pellets
He now eats the medium ones.
I feed:
hikiri gold
hikiri bio-gold (when it is cheap! @ 20.00 a bag it is expensive!)
Hikiri Staple
Cichlid Sticks
All of these are mixed in a large jar and I just sprinkle some in at feeding time that way he gets a large array of things. I also feed him 2 or 3 mealies at night before bed. I also buy a couple ghost shrimp every couple of weeks and toss them in there with him. They never hit the bottom of the tank. Shrimp and mealies are the only 2 live foods he will ever get.
Food is a matter of preference. With the Bio-Gold scientific studies have proven that it lessens nitrate creep which is wonderful for Oscar owners. I have a 55g tank and I do 2 75% water chages a week to keep Nitrates below 5. Personal preference.
HITH is linked to vitamin defects and bad water quality. So the healthier Oscar eats and swims in, The healthier Oscar will be
(I know that I sound like a broken record repeating this stuff but for a person that comes in looking for oscar info I want them to get started on the right page
Not have an un-healthy oscar that gets nothing but feeders.)
