Hi Im a relatively experianced marine fish keeper & enjoy the more unusual species, e.g. seahorses, eels etc. The other day I visited my lfs & saw the most stunning octopus - it was probably very silly of me as I know nothing about these creatures but I couldnt resist. I chatted to the owner of the lfs (very knowledgable & trustable guy) to find out whether I would be able to house the cute fella. He said that he was fully grown & ate crustaceans (I live by the sea so should be able to get a regular supply of live crabs) - it all sounded fairly simple & so I took the plunge. I have put him in a tank of his own with a deep sand bed and live rock (there are a couple of button polyps growing on the rock but I assume this wont hurt him). There is a sump attached to this tank. It has a lid and just a standard floro light unit so I think the set up is ok for him from what I have read. However when I have looked up details of his species it appears he is a mimic octopus which everyone seems to warn against & now Im worrying that Ive made a big mistake by bringing him home. Any advice would be appreciated.
