We noticed that with our first peacock bass, Dozer and Happy dude would pig out and get fat little bellies and in the morning when we got up they would be bigger.
now the new dudes are doing the same thing.. my 3 inch c. ocellaris are now closer to 4 inches and we've only had them a month. and the little tems are doing the same thing, but it's tough to tell if they are growing or not cause they still look tiny next to the bigger baby dudes.
