The amount of food your fish will consume each day is in relation to the water temperature and other environmental conditions. Generally, however, the (that which is consumed in 5-10 minutes rule) is a safe way to go. It is better to feed your fish at a regular time each day. As you continue to do this you will find your fish eager and waiting for you and you will also be able to spot any odd behavior or appearance in your fishes. Always make it a point of watching your fish eat, as there are always the greedy versus the timid eaters. In such a situation, the timid can be fed at one end of the tank, while the greedy is fed at the opposite end. If you feed your fish everyday as a general rule, then if you should have to be absent for a few days or up to 2 weeks, your fish will survive without a problem.
