I saw an excellent octopus at one of my LFS, they specialize in Salt water fish and inverts. I always read up on em and always wanted to get one. It just amazed the heck outta me the way they can change colors so quickly. They just got him, and the owner, who I am good friends with, had me in mind when he got like 4 of em.
Fed one of them and I was AMAZED!!! So, yanno, I just HAD to get one. The hefty 45.00 price tag wasn't bad either. Still have him to this day, and it's been 6 years so far. It's very unfortunate that I have to keep him by himself.
