Help! A bit of a conundrum with my Carnation and its base
I recently purchased a pink carnation and didn't realize, neither did the shop keepers, that my carnation was growing off the top of some species of clam or some shellfish similar. I thought it would be fine since it originally grew on it in the wild but now I think the clam is dying. It has been slightly open about half an inch for a day or two now and I can see the muscle(flesh) of the clam turn and orangey brown color from a bright white. As well it appears to be sheading it's meat. Couldn't help but notice a few of my electric blue hermit crabs paying particular attention to it. They can't get in the clam but can seem to stretch just close enough with their leg to occasionally grab a shred of meat. So my question is, if anyone has any ideas, are the hermits trying to do what they should be doing by disposing of dead waste (if actually dead)? And should I be worried about removing the top half of the shell in which all the carnation branches growing so that I can get rid of the bottom half of dead meat and prevent an ammonia spike which may kill the carnation or poison my other live stock?
My water conditions are as they need to be according to the demanding carnations parameters and I am directly feeding it plankton by pipettes.
I will attach a few photos to help explain the problem
