I have, I love him. He's quite quiet :) but I'm absolutely fascinated by him. I was just wondering how any mussel owners are getting on - there is quite a lot of conflicting information about them. Opinions seem to vary between they are super easy to they are super difficult. I'm taking the view that they are difficult (most creatures are, right) and so I'm trying to boost him with extra plankton etc. Obviously he isn't really the type to wear his heart on his sleeve so any info and anecdotes about what makes the happy or sad/ poorly are appreciated :)
