By feeders I mean Rosies, small fish that look like goldfish they are either orange or silver. I meant by how they swim around and if they have Ich. How can I get rid of the parasites in case they have them, how can I tell if they are infected by a parasite? Also, they prefer either live fish or sinking pellets, that's why I had trouble with the Hikari brand I got, they floated so my Oscars would hardly ever eat them. I tried only putting only 3 or so in at a time and got the same results so I knew it wasn't overfeeding. I'll look for some very tiny frogs or tadpoles if I can find them. How would I get shrimp the correct size for them to be nutritional to them without the shrimp being to big without breeding, do most LFS sell small shrimp? I fed them a worm once which I found to be somewhat cool, no clue why. What kinds of fruit should be fed to them and in what ammounts? I'll try to give them equally feeders and pellets untill I get other foods. I will get a thermometer and tune the temp to the right degree.
Rosies are a type of minnow ie. same as goldfish

. do not buy them anymore. that makes everything clear. you cannot tell if a feeder has a parasite unless its anchor worms or another external parasite. but with internal parasites the fish will appear fine and then die all of a sudden. white poop and bleeding are a few signs but there aren't always symptoms.
with that said you can't always tell if your fish are infected and so refer to my other post with my suggestion of what to do. you can also refer to the parasite sticky on this website for how to get rid of them.
your oscars probably never ate the floating pellet because they can't spot 3 as easily as say 40 pellets in the water. lol
i told you what they eat in the wild. but i wouldn't advise you catch wild tadpoles and frogs as you will get the same risks as feeding any wild animal to a captive one which is parasites.
they should sell shrimp at petstores most of the time. just use your gut feeling whether the oscar can eat it or not. if its small enough etc.
i'll give you a small list of what you can feed them. included but not limited to:
crickets
mealworms
mealworm bettles
small tetras
guppies (swordtails etc)
baby convicts
ghost shrimp
wax worms
tubifex worms... things along that line for live foods.
never feed: rosy reds aka any minnows, goldfish, koi, aka comets, or anything along those lines.
as far as fruit goes you can use just about any fruit but it all depends on whether the oscar likes it or not. you can try berries/cherries too.
pellets are pellets. select maybe 2 or 3 brands and your fine. they are well-rounded "feed all" and for the most part it won't really matter. its just a sub-par way to allow your fish to get by with fair nutrition.
