Crab in live rock - good or bad?

[Kizreef]

Got some live rock for my refugium and this guy dropped out when I was moving it. Type? Good? Bad?? What do I do with him?

Recently had on from live rock, other lived in center of a soft coral, never seen that. The one in coral, looks white and like the Abominable Snowman on steroids. Abominable Snowman in a separate chamber in sump, so ok. Other in DT. No issues

It's a crab so any can be opportunistic feeders. Plenty of threads where members witnessed emerald cards eating flesy coral. Use caution.

Took him back to the store. Thanks all.
