I have a 6 inch decorator crab which will leave any non coral tank spotless. he is free to a good home and I can manage to take a few pictures for you justr shoot me an email and i will have it there right away. i had him in a 5 gallon tank for abhout 8 months he started the size of a quarter and now with his legs and claws is about 6 inches in length and his body is about the size of a silver dollar. If you want him let me know. He would be great for a sump or algae control. thanks and I hope to hear from you soon if not hes going into the big blue sea in south beach.
