I've had a crocea in my tank for a good 6 months and it had been doing awesome. about a week ago a powerhead fell and was blowing directly on the clam. I don't how long it was like that I assume it was around 12 hours, the clam was closed up tight. I fixed the powerhead and it opened back up with in a few minutes. Everything seemed fine. Well within the past 2 or 3 days it's mantle has started to look wilted. it still opens up and the siphon thingy(sorry I don't know the scientific name) is sticking out like nothing had changed. Will it recover? Any clues as to what might be going on? Any info would be helpful.
