from now on i stick to clam chowder

Agreed no less than 1year and none under two inches.
Also consider the clam species. I have multiple clams and my favorite beginner is a hippoppus? They like it on bottom and no foot to bond to ground. They just use there weight to stay put

I think most people kill clams when they damage foot trying to move them

the foot was good on all 3 and where healthy clams when i got them. my water columns may be too clean lol when i do a water change my old water seems clearer than the new water all the time

I have no answers for you unfortunately. Clams over 2 inches, and especially over 4 inches, shouldn't need supplemental feeding. Your lighting sounds good and the tank is old enough, so not sure what could have happened. I have read that Maxima's are the most difficult, hence, I stick to Derasa's and Squamosa's.

I added 1" maxima to my brand new 90 3+ years ago, and moved it several times. It now resides back in the 180 and is almost 3". So you can add to a new tank, moving around is fine if care is taken to not damage the foot, and I've never directly fed it.
While these things can affect them, it's more likely parasites or some disease. We often read about mass die offs every now and then from unknown causes.
Did you ever look for those pesky little snails?

the anser my friend is blowing in the powerhead..lol seemed like a good thing to say.. i just need to take a break from clams i can no longer add one to my 90 due to my trigger so my 50 is all that i can add clams to at this time. and i read maxias are difficult as well. i will leave them to others who can keep them alive

i have never seen any tiny snails just those tiny stars. maybe in a year or so i will try again. but at this rate i feel i am depleting the clam population at alarming rates. some ppl can keep some corals like elegance corals and have them live forever. some cant no matter how hard they try. my duncancoral has bloomed huge in my 90 my dendos havent budged in size. and in my 90 i cant grow gsp if my life depended on it i kill them where others cant control the growth.

its amazing how yoo can have very simular setups and things grow different for different ppl.
