Six Line bothering Clam ?

[Diego Manoel]

Hi guys, someone had a problem with six line?

Friday night I added one in the aquarium.

Yesterday one of my croceas only opened after 5 hours of light.

Today the same thing, the Clam still closed only with a bit of the mantle exposed. However, I didn´t see the six line bitting the mantle (yet)

*** there are no pyramids in my reef ***

Any suggestion?

Useful informations

The wrasse could be picking at snails or other crustaceans

Forgot to say, that there are no pyramids

This behavior remember me when this clam arrived to my aquarium. bougth 2 new croceas at the same time, one always opened with the lights and this one only after some hours. But after one or two weeks it stoped and both started to open toghther.... But the question ir, if it is not the fish, so way the same behavior ?

If you haven’t seen anything fish/ inverts bothering it then it would be the same behavior as before
