A good rule of thumb is to use time as a guiding factor. Most aggressive feeders can easily consume their requirements within two to three minutes, two to three times daily. Fish such as Discus and Bottom dwellers (Catfish, Loaches, Sharks, Plecostomus) require approximately 5 minutes to properly nourish themselves. It is suggested to consult books and knowledgeable pet store staff to obtain specific details about the species being kept.
