How much do you feed your trigger fish?

[daniella3d]

I have a niger trigger and he's always hungry but very very shy. I only have small fishes in the aquarium as well as a copperband so no aggression but he's still very shy. I have the feeling he would eat more if he was no so shy. I feed him twice per day with pieces of shrimp, mysis or live white worms. I also give them a fresh mussel a few times per week and that is an absolute delight for the trigger. He really loves that.

When I skip the morning feeding he's out in the evening and much more bold for the food but as soon as he's full he dash into the liverock. When I put a mussel I don't even see him that day. He's got a cave in the liverock which he does not come out of except for eating. I was hoping that he would get more bold with age but he's now about 6" and still hide all the time even if I have that fish for about 6 months now. Oh well...
