He looks like he's got cyno! Sometimes if the algae in my tank build up it moves into snails, I usually try and get on top algae outbreaks as soon as possible...

It looks fine to me. I've had porcelain crabs that look just like that, not all of them have the red.

My snails and hermits shells are covered in red algae. But there are literally porcelain crabs that come in white/red carapace. I'd get a shot at mine if it was near view, but him and my anemone live in the back of the tank.

Extremely reef friendly. Will clean stuff up, but mainly filter feeders. There is also an anemone porcelain crab, what I have in my tank, that lives in an anemone eating the slime off of it, supposedly, and filter feeding. Cool symbiotic relationship.

2, 1 bubble tip and 1 carpet. Had another bubble tip, but traded it for 50 dollars worth of pods.
