Thoughts on acro crabs bandits

[Eckolancer]

I want to see what everyone's thought on acro crabs are. I found a couple bandit crabs on two wild acros recently. I kinda like them but wanted to see what everyone else thought.

I also wanted to see if anyone know of places to buy them. I may look at getting one for each colony I have. I seen live aquaria has them which I've purchased in the past. But they were larger then I thought (size of smaller emerald crab at the time was to large for my colonies). The ones I've found are about half of my pinky nail size. Will these current bandits get larger? If so how large? How long do they tend to live? I will try and get pictures of my current one that I have?

i picked up 2 acro crabs the other day.
they came as hitch hikers on a shipment of corals at my local lfs.
they gave them to me for free!
the ones i have are approx 1/2 across the carapace.
they both live in birdnests.
