I've managed to find plenty of information on the frequency of feeding, but I'm trying to establish the correct quantity/portion that my 10" gar should be getting "per feeding". I have him off live, using thawed raw shrimp right now (stuffing w/NLS pellets). Right now, every feeding is one shrimp (medium sized from grocery). Currently feeding him once per day. This enough? The fish seems to still want more based on the reactions to me being near the tank after he has already been fed.
