5 clams dead :(

[Uncle99]

That's what I thought originally but why would they suddenly stop and leave one alive after killing 5 of the other clams if it was them? I just dont know. That's what makes me think it was something else.

It certainly could be someone else just this fish eats clams in the wild so…..

After six months oil the DT, Mine did two, first a dersa, then a month break, then a Crocea. At this point I started adding more food in terms of frenzy which contains clams and I still have three left.

Been good for a month now. Not convinced it’s ended though….hope…hope…

Sorry for your loss, clams are not cheap.

Absolutely, its just they lose their foot as they get older and their weight then supports them? These were quite old clams. Especially the huge maxima/squamosa cross and the other maxima so it was normal that these didn't have their foot I believe

I will start by saying that I don't know enough about the life history of these creatures to give a legitimate, factual answer to how what I will call Medium Sized giant clams dwell in the wild, with our without a foot (and the attachment intact.)

My personal observation is that newly settled Giant Clams quickly burrow into the dead reefs or into living coral colonies so that their feet are not readily exposed. There mantle will open to collect sunlight, and presumably they filter feed whenever they are open and siphoning water.

At some size the giant clams do seem to become detached and free living but it seems like there are not a lot of medium sized clams living, attached or not, in waters I have swam around in. Lots of 5 inch or less clams are attached on rocks in the lagoons, and fewer offshore in the coral heads. I have concluded that the transition between attached and free living LARGE giants is a high mortality life stage for clams, but I don't have any experimental facts to back up my casual observations.

Except, this, small clams that are detached on the reef are generally found dead whereas their buddies that are sheltered inside of a rock or coral "nest" seem to be protected and able to live happily without predation.

To that point, I know lots of folks have cut depressions in rock for clams, and maybe even some that are quite form fit to the clam, but has anyone tried to determine if clams in a mold have a higher success rate?

Perkensis, extremly common with wild clams these days, those that survive are carriers fir life

It's interesting, because I dont have a sand bed either so they were literally sitting on the bottom of the tank. Maybe its worth me getting another and seeing what happens.
That perkensis parasite is an interesting theory aswell i might have to look in to that. Is there a reason why the surviving clam didn't die from it and why they become carriers?
