Crocea clam

[Delphinus]

I find with new clams I have to put them into a spot with a real depression in the rock that they can fit into. They do like to wiggle around a bit and in the flow can get knocked over or pushed over by snails, urchins, etc. I find even making a little fence of rubble isn't usually good enough (maybe if the rubble was epoxied so that it can provide some resistance to the knock-down). But the right indentation in the rock and suddenly after a couple days they're stuck like superglue. And of course orientation is important - an angle probably isn't good either, they like to be flat to spread out to embrace the light.

I have 5 croceas and all are on rocks, I'll agree they are hard to get on the rock here are some suggestions to help you....

Find a rock that is slighty convex sort like an upside down saucer place the clam in put a few rocks around it so it cannot fall out sort like baby in a craddle they will attach overnight. Another thing to keep in mind if once attached to the rock make sure they are always facing up cause sometimes if they are side facing the weight of the clam is too heavy for the legs and they end up releasing happened to me before aswell.

The only one that doesnt take to rock in my tank is a gold clam, derasa?

It just sits on BB tank and moves around on its back the legs don't anchor either, kinda weird.

Thanks guys I found a nice rock with a depression in it that the clam fits right into. Hopefully it will stay. I am not sure though if its foot is actually even touching the rock It seems like maybe the foot it now suspended just above the rock a few mm. I am going to leave it for now and see what happens.
