Scarlet Crab in the Fuge...Good or Bad?

I have a scarlet crab which has gotten pretty huge. I have been keeping a close eye on it and constantly picking up things it has been knocking over including coral. I didn't mind picking up after him too much but when I saw him picking at my brain coral I said enough is enough and I put him in the fuge. He has lots of room in there and does one heck of a job keeping my chaeto nice and trimmed. Last night when I saw him rummaging through the sand it hit me, he's going to clean out my pod population. Am I being paranoid for no reason or is this guy going to clean me out? I do have lots of pods in my DT and there are tons climbing through the chaeto that he can't reach but am I making a big mistake having him in there?

 

I don't think the crab will be able to do much to the pod population. They are a lot quicker than any crab
