I bought 2 small(2 1/2 inches) croceas a month ago they both looked good after a few days one of them had one side of the mantel retracted the other one looked fine after a few days the ill looking one died and a few days after that the one that looked good died with no warning.
Since the death of these clams i added a phosban reactor with phosban media and another one with super activated carbon.Sunday I purchased 2 more croceas same size as before acclimated them and one of them is showing the same signs the mantel on one side is not opening all the way this happened after one day in the tank . The only thing I didn't do that I see I should have after spending a couple hours on this site ( clamsdirect)is acclimate for lighting I placed the clams in the center of the tank .
My tank is a 125 rr with a 40 gal sump with a refugium running calurpa, 3 150 watt 14000k HQI MH, 4 96 watt pc 2 dual actinic and 2 10000k (I usually only keep the atinics on) all the bulbs are a month old I have a aquac ev120 skimmer , 700 gph closed loop on sea swirls, 1000 gph return on sea swirl, mj 1200 moded supposed to give 2500 gph, 2 phosban reactors as mentioned above, korallin calcium reactor with ph controler running arm media, ground probe, 200 lbs live rock lps and sps, nothing close enough to sting clams , 3 cleaner shrimp, about 25 cerinth snails,about 100 turbo snails, about 30 red leg scarlet hermits, some blue leg hermits, maroon clown , percula clown, six line wrasse , pencil wrasse, 3 dispar anthias , 2 chromies , bicolor blenny,
the tank parameters are everything undetectable except nitrates sometimes get to 5, alk 10 dkh, calcium 420-450 I don't have a magnesium test kit but i have to get one
Please note thru all this I have a crocea clam 4 inches for about 4 months healthy and have had clams in this tank before but sold them cause i thought I was getting out of hobby. The tank is running 5 years and for the past 2 months I have been doing water changes religiously 25 gallons every 2 weeks. .Before that 30 gallons every month. I feed the tank DT's phyto. I spend most of my time sitting by the tank atleast 3 hours a day and never noticed anything pick at the clams I also look at night with a flashlight checked for pyramid snails the only thing at night that I saw was a couple spaggeti looking worms very thin retract when light hits them they are on one rock were the sick looking clam was ( same rock the first clam that died was on) but no worms near the other clam
