I have an oscar, he's about a year old, and has always loved his food. Just recently, he actually stopped eating, and now is somewhat picking at his food a bit. I tested the Ph (it's fine), nitrates are fine, I don't know what is wrong with him. He appears to be very healthy, he has turned down beefheart, krill, blood worms, etc., so we went and got a few feeder fish, because he NEVER turns them down, and he is actually swimming around with them
OK, maybe that's not funny, but he is about 12-13 inches long, and hardly the type of fish that likes to swim in schools with little feeders. Anyways, I finally got him to take the occasional cricket, and sometimes some brine shrimp flakes, but not much, and the limited dies can't be good for him. Any ideas? If the ground wasn't so hard and dry around her, maybe I could try earthworms, but I don't have a lot of those in the yard (need more rain).
Suggestions please
