Maxima clam questions

[rgaleana2009]

Hello team, hope you r great. I have had 2 maxima clams for 6 months but now I can see their mantle is a little more elongated, so wondering if some of you can provide me your advice to know if they look OK or maybe I need provide more light. BTW I have tried to get a parmeter but it is impossible here in Mex

Here is a video of them, your comments will be greatly appreciated

Big floppy mantle's are a sign of a happy clam, not necessarily that it's reaching for light like you expect when you see coral extend.

The easiest way to tell how well your clams are doing is to interrupt their light source with your hand and cast a shadow over the clam, they should react and close up somewhat. When they do that, look at the edge of the inside of the shell that's normally covered by the mantle when extended. You should be able to see some pearly white shell. This is new shell growth, and the more of it the better the clam is doing.

They look beautiful to me! I'd just watch out for that bubble tip! Mine likes its personal space, and will kill to protect it ;Nailbiting

Thanks Joel

Do they have new shell growth? I mean significant like 1/4 or 1/2 inch and not just a MM near where the mantle is. This is the only positive-positive that there is with clams.

Mantle extension is fun, but not a sign of much. Clams that are well fed (light) do not always extend as far as they can.

It is good that they are still alive after six months. Without new growth, they could still be time bombs. Sometimes, Tridacna look great for nine months or even a year and then all of a sudden die in a few days - they were slowly starving the whole time. Only fresh shell growth indicates that the clam is thriving.

My 1" maxima which I've had only 1 month from a fellow reefer has MM white area when mantle retracts. This has appeared in just a month.

Hi jda, thanks for your answer. Definitely they have new shell, I can tell they are growing

BTW , so do you think is too much extension to their mantle according to the video?

Those clams look great. I agree with the above if you are seeing alot of new shell growth you are doing something right.

I notice that older clams will have spectacular mantle extension. I've seen 15 inch long squamosas that have mantles as wide as their shells!
