Black Crab with hairy stripy legs with yellow tips

[AyeAye]

I had 4 fish deaths recently all Blue-Green Chromis. I have only one left. I suspected a water change gone wrong, fluctuating water temps, water quality maybe. my chalk white goby's a murderer?. etc... anything could have happened, Then i look inside the large hole in a rock the Chromis use to call home and sleep in at night. I shine a torch and I find this thing. Shape and size its the same as my emerald crab but this one is black with yellow tips on its legs. So regrettably i took a hammer and chisel to the rock until the crab ran out of options.

Its still alive...Let me know if you know what it is, many thanks in advance.

AyeAye

Pointy claws almost always mean predators. That's probably your number 1 suspect.

Dark pointy claws are always bad news.

Kill it with fire.

It looks well fed

Great looking crab but reckon that might be the culprit

It looks like a black fingered mud crab.

Thanks all. The pic you found looks just like it. but I type the name in Google and it's bringing up a very different crab.

LFS has him now.
