I just saw my Purple Tang rip out a blue-legged hermit crab from its shell, and began to eat its exposed end. I guess he couldn't wait until today's second feeding.
Do any of you have tangs that have done this? Will this be an ongoing issue?
Nope, but my tangs to eat meat. I feed a mix of mysis, fish eggs and chopped shrimp and the tangs love it. Sounds like you need to supplement the algae with some meat.
I've had him since he was the size of a silver dollar. I guess he's just coming into his own. He's starting to attack the Kent Scraper. He even tried to slash me when I was mounting a frag.
