I've been feeding my Serpent algae wafers for the past three months. He's never rejected them and loves them. I just read on Live Aquaria that they are carnivors and should only be fed meaty foods. Am I slowly killing him by feeding him algae? Should I switch over to meaty foods? If so what would be good for the sea star? Also should I slowly ween him off of algae or just pull a switcharoo?
