How many pom pom crabs?

[zbrusko]

How many pom pom crabs could I have in a 100 gallon reef? I have 3, I think, and am curious if, for the sake of argument, 20 would be ok.

I have 2 in my 150 and I am lucky to see them once a week. 20 might I crease the chances of seeing one.

I guess a better way to ask is this:

I have 100 gallons & plenty of hiding places. I like them, but rarely see them. If I add a few every time I reup CUC, do I run a rusk of starving them out, or territory issues, etc.? Can they live in large quantities without issue in the hopes I see them more often?
