Whats wrong with my Clams?
 

Ive had these for over 6 months now and they were doing great. always fully open. both under halides and LEDs

all corals and fish are fine.

in the last couple of weeks, this has happen. They seem to be closing up. anyone knows whats going on?

Its a pinched mantle. A freshwater dip can help with that.

pinched mantle on two different clams at the same time??....seems unlikely....how old is your tank now mang?......whats your fish list ATM?

tank is a year old.

fish:
regal tang
black shoulder tang
powder brown tang
foxface rabbitfish
solaris wrasse
cleaner wrasse
mystery wrasse
mandarin goby pair
clarki clown pair

the only fish i ever seen picking at the clams is the clearner wrasse, but i double he's doing any harm

also, seems like this one is slightly more open at night, but still nowhere near where it was 3 weeks ago

If I had to guess I would say that one of your fish is developing a taste for clams. Try putting a strawberry basket or some other sort of protective cover over one of the clams and see if it opens up again

Thanks for the suggestion. I'll try that

Totally a fish if opening up more at night.
