I just watched one of my black longspine urchins that I've had for about 4 months now eat a track up one of my $80 ORA Acro frags and crawl back down. This would explain why 2 of my other Acros look like somebody has scraped flesh/skeleton off with a potato peeler. Has anybody else seen this happen? I have recently started scrubbing and blading all of the algae in my tank to encourage these algae-eating machines to turn their hunger on the coralline that is starting to get out of hand. Has anybody heard of them doing this before when they're out of non-calcaerous algae? I've had them for 4 months and they've never once damaged a coral until the last few weeks! Only sps as well (not including my Hydnophora, but I think they'd have to have a cast iron stomachs to eat a Hydnophora).

Yep!
Is the urchins spines all black or are some of them white? the one's with white spines will eat some corals.

Yep!
absolutley, alot of urchins will eat corals. As well as some are very venomous (usually never available in stores, but they do occasionally get collected and sent as something else)
