Acro Crab?

[T$sps]

I found a little crab, just smaller than a penny. In an acro colony I bought. Just wanted to make sure it wasn't gonna ruin anything.

Uhhhh.....not necessarily Kbra. Not all crabs found in Acros are safe. Many will slowly eat the coral.
If it is brown, black or other darker color and has a fuzzy looking body then it could be very bad and will eat your Acro. If it's brightly colored and has a smooth looking body then it's most likely a commensal Acro crab.

Crabs are good

I have seen tiny white colored crabs eating the acro, about 1/8 to 1/4 of an inch. and area around the crab was destroyed, why take a chance?

white crabs really eat the acroporas or protect them? I thought he was harmless.

The white acropora crab with a black band across its eyes are also called bandit crabs and are considered reef safe , they eat the mucus of the coral as well as any food that may drift in their space. In a nice size acro colony they add a nice touch to any aquarium.
