Anything you can feed new fish to get them eating and properly acclimated to aquarium foods is a plus. It really doesn't matter what the nutritional value is in the beginning as any food can be soaked in a liquid marine vitamin to boost it's food value. Once the fish is accepting the foods, you can start altering them until you find something nutritious it will accept. I am very suprised it does not like the cyclop eeze but you might also try a herbavor flake or possibley mysis shrimp. I don't know if it's available to you but cyclop eeze is also available in a flake form.mansiz said:My bi-colour angel is not eating anything, its just keep on finding food source from the LR, but the food source there are limited, it seems like it is getting weaker, my water parameter is alright, do they really need brine shrimp in order to start eating?
