I got my 55 gallon tank with my tiger oscar and jack dempsey cichlid and they won't seem to eat now . They use to go crazy for food and now they just look around the tank and and when they get close to the food they turn away. I feed them regular pellets, but i have some krill in my freezer...should i try to feed them that? Any tips on how to get them to eat would be great. On the rare occasion i forget to feed them they get pretty angry with each other....that's why i don't have a green terror anymore. I don't want another bloodbath! plz help
