I don't feed mine. They eat whatever they find and they find a lot. They took care of my aptaisia and are busy eating anything and everything including flakes, pellets, and.. me. That's right. I had one walking on my arm the other night while I was trying to set yet another leather coral
frag on a rock. I didn't see him there until I felt a pinch on my forearm. Are they usually aggressive? I know mine aren't particularly shy but I didn't expect that. Go figure.
