I have had my a. frnatus about 2 months It have grown about 3/4 inches to 2 1/4 inches in that time based on photos. I have tried the once a day "saturation" feeding as sugessted by carlos and dare not take it any further than 15 pieces of spectrum thera a (in one sitting once a day) but the little pig comes back for more. the other fish eat a mix that I make up of vitamins shrimp squid and scallop that is finely grated. he only eats dried foods wont touch the gourment menu!
