Hello. I've recently upgraded tanks and have gotten a dwarf fuzzy lionfish. The first day i had him I gave him 3 ghost shrimp and he gobbled those up. Then the third day (today) I have him the head of a silverside, he ate that up right away. I've heard that it's best to feed them 3 times a week. I would do Monday, Wednesday, Friday. My question is how much to feed him. He is about 3-4 inches long including fins. The silversides I have are 2 inches long and the krill/shrimp I can get are 2 inches long. Should I feed whole silversides? Whole shrimp/krill?
