Clams Dying :(

[familiar1985]

i lost a small maxima and a crocea allready. This morning i noticed another small maxima is unresponsive and sunk in the shell. I dont understand whats happening here. All parameters are fine. Why are they dying 1 by 1. I completely didnt expect this. Really frustrating.

I had the crocea for like 3 months. It was on sand and started losing some color so i put it up higher. I then purchased 3 small maximas and placed them up high to start. They were fine for a week or two and then start dying 1 at a time. First i lost a maxima,then the crocea, now another maxima lookin bad.

should i freshwater dip?

small clams need more spot feeding than older clams... how often do you do this?

the polyclad makes sense as well... they camoflage themselves to look like a mantel

i didnt find any polyclads. 3 clams died, 1 maxima and 1 deresa left that are doing good. Im not sure what caused this. Im guessing flow or some kind of illness. Whats for sure is it killed them fast. Maybe a couple days from looking healthy to sunk mnatle. I tried freshwater baths but it was probably too late.

i spot feed couple times a week, in general areas. Not right up to clam. I turn off return for an hour or so when doing this.
