If you guys want to find one, just ask your LFS if they can order from "sea dwelling creatures". I see cuttlefish on their stocklist sometimes, including flamboyants. Segrest gets them too but VERY rarely.
I just wish they lived longer than a couple of years. Back in school we had a pair for a while...then they laid eggs and died. It's tough when you want to breed something, but it will die after. Such an ethical dilemma!
