Hello everyone, I am posting this today because I'm having a bit of a problem with my aquarium. I have a 75 gallon tank with three fish in it. My three fish are a Orange Tiger Oscar Chiclid(about 10 inches long), a Jack Dempsey Chiclid(about 7 inches long), and a Florida Spotted Gar(about 1 foot long). I am currently feeding them chiclid pellets(for the chiclids obviously), shrimp, and occasionally some rosy red minnows. By the way, we recently purchased this tank from a friend who moved. Anyway, the Oscar pretty much eats everything I drop in the tank and does it fast, if the Oscar is busy, eating something else, the Jack Dempsey moves in and takes the rest.I was wondering how I get some food to the Gar (Is there anything Chiclids won't eat that gars will?) and what some nutritional foods to feed all the fish. The Oscar is the boss and controls almost everything in the tank, I really wonder how to bypass this. The Gar used to eat goldfish (What the previous owner fed them), yet still not as much as the Chiclids. Then I did some research and found that goldfish are not nutritious and can carry diseases, so what can I feed them and how can I get some food to the gar? Please respond as soon as possible.
