I have 3 Sunset thick-lipped gourami and I was wondering how much should I be feeding them regularly? I’ve been basically guessing by feeding them as much their two eyes are together since I heard a fishes stomach is the size of its eyes. However, I have 9 harlequin rasboras that peck off their food as well. What is a rough estimate on how much food I should be feeding the group (ex. bottom layer of a bottle cap)? I feel them twice a day.
