Oh, gotcha. That makes more sense. Rule of thumb is a fish’s stomach is the size of its eye, so keep that in mind when feeding and considering portion sizes and frequency.
fish prefer to eat smaller meals throughout the day but that can be hard. I use an auto pellet feeder that goes off 4 times a day and feed frozen every other day and nori when I’m not lazy ha
For a single fish you’ll want to feed really light, over feeding will just result in uneaten food and increased nitrate/phosphate in the water that you’ll have to extract to keep corals happy.
