Don't throw it away, it's not the crab's fault somebody moved its house into your tank. It's a pretty crab. Keep it in your sump or give it to someone who wants it, it'll probably grow into something neat.
 
THANKS FOR FEEDBACK.

After catching this one, I was surprised to find another one inside the tank. wow, I need to use crab trap to cath it. I don't. this alien in my tank to proliferate, they looks ugly and they are growing bigger and bigger.

Cheers,
 
looks like a mithrax. claws are flat tipped for algae. big claws though. may not be safe.
Totally agree that it looks like mithrax. All crabs are opportunistic, but I wouldn't assume they're harmful without evidence of bad behavior.
