Little Clam

[DmitryB]

So I got a small Crocea from Biota. It's probably 1.25''. Came in on Friday, so still him on the bottom of tank to adjust to light. How long do you acclimate them to light in one spot? And is it different with baby clams vs. grown?

Also, flow, that eternal question. In this video, is this flow too much? It's a rotating Orca on chaos, so it changes all the time. But what's happening with the mantle here, is this ok? Too much? Not enough?

Clams can adjust their exposure to
Light and generally enjoy as much as we give them under our lights. No need to acclimate them. The current is fine, the clam mantle is able to remain expanded, and not constantly crumpled or folded in the video. Too much and they will retreat and fold up.

I believe that clam wants a fair amount of light... 250-300 par. I would personally be looking for a home at least 1/3rd, maybe 1/2 way up the tank.

I have some Croceas sitting in about 300par at the peak of the day. I never acclimated them, just sat them where I wanted them. They seem to be growing and doing fine. Mine sit in the the middle of my acros.

Alrighty, no light acclimation then! He's going up tonight! Though the flow is also higher the higher you go, so we shall see!

What about feeding smaller clams? There's some conflicting info out there. (Crazy, I know!) the old school was that any clam smaller than 3" has to be fed, but the Clam Mania guy seemed to dismiss that in one video I saw.

Mine seem fine getting hit with alternating gyre flow. The mantles blow but they don’t care. I don’t think they need food, but if you want to dose phytoplankton I’m sure they’ll eat it.

I broadcast feed coral food, which he may be able to grab. And I do dose Phyto. You think it needs a direct feeding or broadcast is enough?

I’ve never directly fed mine, just dose phyto and oyster feast.
