Ok I have 6 small 2-3" oscars and when i first got them they were pigs and now they don't want to eat, they eat what they have to they look maulnutritioned and they are in a 20 gallon tank right now, there is plenty of room i will be only keeping them in there for a few more weeks before i put them in my 100 gallon tank, filteration is not the problem either neither is water changes, what should i feed them i have tried everything,i have been feeding them shrimp and chopped up fish (like perch and stuff) they seemed to LOVE that for like a month now they are not eating it like before and only eating what they have to like i said before is there anything that i can try to feed them and if so what? there is also one fish that hasn't eaten in like 3 days, he is alone in the corner there is noting wrong with him other then he is by himself and not eating, i have to put the food in a funny place (you know just to see if i could get him to eat it) and he would swim up to the top and not even take it
please help
