how do i know my new fish are eating? i have a 100 gallon oceanic tank with a 6in albino oscar in it that eats like a pig, so i decided to add some more fish, so i bought some smaller chiclids to grow in the tank. so i bought a bunch of drift wood so they have hiding places from the oscar. i feed the oscar chiclid sticks that float on top of the water and it come up to get them, but none of the other fish do. the other fish are a jack dempsy a jewel chiclid and i think a fire mouth all about 2 in long all they do is hide. how can i feed them or what kind of food should i buy i want them to grow with out adding a ton of food that is not going to mess my water up? thanks, im still a noob and trying to learn from every body on here how to care for my fish and tank the proper way thats why i ask questions like these.
