I am setting up my first saltwater tank and ordered live rock and sand from Tampa Bay Saltwater. Other than the assorted tiny crabs I didn't think I got any hitchhikers until we noticed a gorilla crab, while we were getting him out of the tank we found we had other stow away that we didn't know about. I found a tiny little octopus who had wedged himself back into a little cave in one of my pieces of live rock. I haven't been able to see him out and he's really trying to hide. From the one time he moved a little to grab a piece of shell to hide himself with I think his tentacles are about an inch long and he is a reddish brown color. Every thing I have been reading and all the advice I've been getting is to get him out because he will eat my clean up crew and anything else I eventually put in my tank. Right now all that is in my tank is a serpent star, cucumber, peppermint shrimp, turbo snails and blue legged hermit crabs. I would like to eventually have two clowns and a goby. I think the octopus is really neat but it wasn't my intention to create an octopus tank. Any advice on if I can keep him and still have the reef tank I wanted or if not how to get him out nicely so I can take him to my LFS so he can hopefully find a nice home. I think he's been in my tank for about two weeks now since I think he came in my second shipment of rock. BTW my tank is a 14 gallon Biocube. Any advice would be great!
