Hi Experts, Found this crab today (about 1.5cm)... not sure if it is good or bad. Thanks.

Really blurry pics, but in general, banish all unknown crabs to the sump. They're just too risky.
Thank you. Are there a list of good crabs for reef tank available?
 
Fiddlers , barely. If hairy- a no no.
 
Most tiny hermit crabs are a good place to start. Some recommend emerald crabs, and there are cool ones like porcelain crabs and anemone crabs that are also sometimes good.
Thanks.
 
If its hairy or has sharp pointy claws its probably a no.
Ive gotten black crabs that look like emeralds but get a little bigger.
Look up gorillia crab hitchhikers. You might see your guy.

Been looking for it but not able to find it yet... hope i can catch it before it is too late.
 
If u cab find the rock he hides in. Pull the rock and fw bath it to remove the crab.
U can look at night time with a red light or black uv/blue actinic light. U might catch his red eyes. Glad i could help.
