I have 2 Clownfish (Ocelaris) , 2 Dotty backs (Neon and a purple) and a fire shrimp. Currently we are feeding them a small pinch of flake food in the morning, 2 small brine shrimp cube in the afternoon and another small pinch of flake food at bed. Is this the proper amound/type of food to be giving? They seem to like the brine shrimp the best. How much is too much and how much is too little. The local LFS all have different opinions. Just looking for some insight. Thanks!
