Feeding is a critical part of raising your fish. Too little results in small fry that will have difficulty surviving in the wild. Too much results in tank chemistry going out of balance. The fish should only be fed what they will eat in a session. First feeding is “tease” feeding where you sprinkle food to see if they eat it. Later you will find the right amount to feed at a time. This amount increases as the fish grow.
One way of keeping feeding under control is to have a table to record food amounts and the type of food. See the Teacher Handbook for more information on feeding and use a table to record. The table record not only tells you the trends, but if the students fed the fish. Get the template HERE.
