Come on guys, please keep it civil. Disagreements are fine, but tempers are not.

Dez, I never got mine to attach to rock either. I read the Knop book to my clam, but he ignored me completely. He checked out after a month or so in my tank .... but I had another clam perish prior to that, and it seems that if one goes in your tank, the tendency is for all of them to eventually go. :cry:

Generally speaking, I don't feel right about it if something isn't acting as it would in the wild. If it's supposed to attach to rock, and it doesn't, then I'm tempted to beleive that there is something that "isn't 100% right." It may be trying to find the right combination of substrate, texture of substrate, flow conditions, lighting, etc.

When I had asked around about my squamosa, I was generally advised to not worry about it. If it stays put in the sand, then let it be. I guess one other thing I've noticed about clams is, the less they are pestered, the better. Constantly adjusting this or that, because you think something might be better off for it, isn't necessarily the best course of action ... better to go slow. Actually, the ideal situation is that it gets put into the final spot as soon as possible, and get the stress of being handled over with.

So I guess, ultimately, go with what seems to be working. If it stays put, then that's probably good enough. But if it's scooting about, then it's probably looking for something, which means it's not getting something that it's currently looking for, and some sort of corrective action should be considered.

Thanks Tony,

I have considered putting my squamosa on a half clam shell so that it could attach to that, but I want to see whose had one for years. I know that Maximas do well when attached. Hmmmm.... any other opinions?


Des

Just to add a bit here....even the maximas and croceas apparently expel their foot when they get large enough for their own weight to hold them in place, so they end up not anchored at all.
And I have never ever seen a squamosa or derasa attached to a rock(YMMV)

Great images as always Sam :exclaim:

cheers Rich :mrgreen:

The clam on the left was a T. squamosa that remained attached to the rock it was on for well over a year (it was only about about 3.5" however)

The Squamosa is really taking off. Here's a pic with its shell closed.
