Hi, I found this little Occy while snorkelling round some reefs here (South East of South Australia) and I brought him home to put in my marine tank. We poked him around at first with the blunt end of a skewer, because we thought he was a Blue Ring, but after a few colour and pattern changes, there we no visible blue rings (which is why we kept him). Can you tell me what kind of octopus he might be?? It's about 6-7cm long (from tip of head to end of tentacles) and is a light brown colour, and turns dark brown when prodded. My husband is a proffessional Rock Lobster fisherman, and said he's never seen such a small Octopus, the ones they catch come up in the lobster pots and so are pretty big and have usually eaten all the lobsters! Thanks, Tracy.
