One of the most important factors in successfully maintaining your new aquatic habitat is following the feeding instructions.DO NOT OVER FEED!The Biota Aquarium comes with a food packet and a measuring spoon.The fish should get one spoonful two times per day. The best time to feed is after the light has been on for at least 30 minutes and again before the light goes out.Feeding should be at least four hours apart. Your fish “sleep” too and eat best during the times when the light is on.
