My question is specifically about angelfish, but I suppose it applies to other species. I am wondering how much if at all feeding frequency and growth rates of juveniles affect ultimate adult size.
I know that some Discus keepers feed four or five times per day and change 50% water DAILY to get rapidly large fish. Good for them I say, but what if instead they fed 3 times per week? Certainly they would grow large more slowly, but would they be runts in the end, or even much smaller at all? I am trying to avoid the heavy water change regime that comes with heavy feeding a school of a dozen juvenile angels. Even when they eat every morsel, the water is ultimately degraded by so much food and waste that I want to swing the pendulum as far the other way as I can. Would a good robust feeding 3 times per week grow out young fish without any adult size sacrifice?
Youngsters need food to grow, so at what age would it make sense to make food just a little scarce?
