Looks like a good sump resident lol.

I would sump it. I can't say for certain what kind of crab it is but better safe than sorry.

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.

looks like a mithrax. claws are flat tipped for algae. big claws though. may not be safe.

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,

Rock crab. Put it in the sump.

They aren't breeding in your tank, crabs have a planktonic larval stage. You just had several hitch-hikers.

 

[peasofme]

yea, the odds they could breed in your tank is very slim

Totally agree that it looks like mithrax. All crabs are opportunistic, but I wouldn't assume they're harmful without evidence of bad behavior.

i'd say it depends on what u have in ur tank and how much u care about it. it can be a risk.
