Unwanted crabs...?

[toytech]

Everyone seems to be drinking the bristleworm haterade latley , i have hundereds in my 15 gal nano they come out of everywhere , the rocks ,the sand , and honestly the tank has never been so clean .Any leftover food is gone in minutes , and they dont bother my corals or fish .Granted if they get big they get REALLY creepy but i wouldent worry about the little ones , and besides if theres one there are probably many , many , more .
