What tank mates for this guy? Also, ID?

[VFX]

Ha 7-11 crab! I like it! Thanks for the ID.

I knew he'd be destructive but my g/f loved him so much that I had to get him. He's been keeping my chaeto company & feeding on pods & baby cleaner shrimps ever since. I feed him a chunk of fish meat or crack open a clam for him about once every 2 weeks.

He's grown about an inch or so in less than a year,

It'd be nice to find a female for him but they'd probably fight to the death in such a small space.

So no other tank mates for him?

He'll have to stay lonely?
