pictures would be great, but just from your discription the only crab i know of to be white with speckles, is a porcelain crab (Porcellana sayana) they come in different color variations. the one i had was all white with red dots. they will not do harm, as for many crabs are good for the reef tank, as they sift sand and keep the rocks clean.
