Hello Everyone! I am a new caretaker for my first abdophus octopus. He/she arrived on Tues. from Drs F & S. I have him in a 34 gal tank, and today he ate a ginormous crab. I am including some pics, and if someone ID's him as something else, please let me know. This is truly an amazing creature. Thank you for all the good information I gathered prior to ordering this octo. One thing I noticed, is that he likes to curl up in a corner about halfway up the tank, on the glass, even though he has lots of rock caves.
