It's not frequency that causes problems; it's quantity. I feed
miniscule amounts several times per day, no single food
more than 2 or 3 times a week.

The key is to provide food as close to how it is provided in
nature as possible. In nature they have food in constant
supply, so we should feed them several times per day
(small quantities) and this is proper regime for all fish except
predatory carnivorous eating whole fish/shrimp like eels/gruppers.
You are doing good. Feeding rare, once per 2-3 days is not good.
