my sand sifter seems to have a bite taken out of one of his limbs its a tiny bite but right at the end of it. worrying bit is theres no fish in the tank. Assuming it wasnt the hermits or snails theres a peppermint shrimp and 2 cleaners in there atm all tests are good just a bit worried about him any thing i can be doing thanks in advance James 
will have to keep my eye on him
