That is sad! You think the bahama star ate him or is just cleaning up? Tuvalu was a really cool octopus and you got some good footage of her. Saltwaterfish still has their octopuses on sale so at least that's a plus if you want another Filosus.
I'm pretty sure it ate her. Every single time I fed her there was Mr. Bahama Star trying to climb on top of her. She usually climbed into a crevice somewhere to eat so I imagine she did the same routine, and got trapped. The star is twice as big as she was. I had been looking for her since I got home this afternoon, and I kept noticing the star near her den, in the same place for a couple of hours. I finally decided something wasn't right and picked up the star, and there she was, halfway underneath the rock with a dead crab. There wasn't anywhere for her to go, so again, I'm pretty sure it trapped her and inverted its stomache... *explicit language goes here* I failed her. I remember reading someone elses post about the same thing and thought, "surely there was something wrong with that octopus" but at the same time, I knew the nature of this type of starfish. Geez... taking Mr. Bahama Star to trade in at a LFS sometime this week or maybe put it in the sump at work.
I am going to order another one, probably tonight. But it won't be Tuvalu *sigh*
