Make sure the clam is up really high under pc lighting. Like as high as you can. Also make sure your bulbs are not very old. Also if it was under MH lighting it may take a while for it to adjust. You should always try to mimic the lighting that a clam is under in the FS if it is doing good. Well good luck and if you have good pc lighting it should be ok. JUst make sure you other water parameters are good like calcium/alk. They need lots of those elements to grow

I have a derasa and i only have pcs and it loves to sit on the sandbed instead of the rocks.

no problem. im usually trying to help, but for some reason my posts come off as rude to a majority of people.
what can i do.
anyway, the clam does look sorta tense. he shouldn't be that tight. does his mantle usually extend out more?

well constantine thats just the way you sound....
now back to the clam. hard to tell without seeing the true colors (original before you owned it) but it could be some localized central bleaching the central tract looks kind of pale. often due to light shock (too much or too little light too quickly, but not always) the tightly closed siphons may be because it is trying to expell dead zooxanthellae from its flesh. sorry i cant be more helpful.

When I first got it opened up in my acclimation bucket (had a low watt floureescent, then i only gave him 3 hours of light that day) and as soon as I put him into my tank. On a chunk of live rock (covered in a thin layer of live sand) over halfway up. He opend up right away but it was several days before he fully opend up and really started filtering so i could see all his openings. You don't want them to open too much either cause this could mean tehy are lacking someting they want. Good luck I know I need it.

Thanks for your help, guys. I don't have the camera anymore, but the clam is now about 3/4" below the surface of the water, right in the middle of the tank where fluorescent lights give off the most lumens. His mantle looks pretty much the same as in the pic, but I did some reaquascaping and the water's pretty dirty.

ok this is basically the same problem im having i think ive had my clam for about 4 days now and the pic of your clam looks kinda like mine, i do need to do a water change but the water parameters are not horrible
i did take my clam out of the tank and placed it in a glass bowl with water from the tank and put some dt's in the bowl, the water did get a little more clear than when i first put it in but its still not all the way open
i have a 37 gal reef tank with 97 watt pc light, the only thing i didnt know was the water flow, mine is in a low flow area on the sand bed should i move it up closer to the light and in more flow ?
i will try to post a pic this weekend when things kinda slow down for me
any info that you guys can give me i will appreciate
thanks

what does your clam look like exactly? does it look bad?
Squirting DT's and the bowl trick is not a great idea for clams at all...
For the most part once Clams mantles and flesh loses the color and they turn somewhat brown..They will never re-gain that color again..

I woke up this morning and my clam had died. There was basically nothing left of him, save for the shell and a couple of pieces of his outer mantle. I can see a few chunks of tissue floating in the tank, but I'm wondering if something ate him. I have hermits, snails, a false perc, and a coral beauty. I know the coral beauties are known to munch on stuff, but I've never seen him touch any corals and he never even took a second look at the clam. It's hard to believe he'd eat ALL of the clam (which was bigger than him) at once when he hasn't even noticed it before. Do you think something ate him or did the clam just die?

More than likely the clam died, and then the crabs took care of the remains..They seem to work rather fast..

why not a friend had a clam for at least 2 years until he sold it, he done this once a week and it was huge by the time he sold it and he also had this one under some plain old flourescent lights just to prove a point to the lfs so .... it worked for him for long time,
and if he was still around i would not have wasted time posting on this topic

good for you,i just know what he did worked and worked great, do you do everything by the book, i dont and im pretty sure no one here really goes by the book anyways, as far as i can remeber the clam never was attached to any rock.
like i said before if he was still around i would have never wasted my or your time with this posting, if i can find some old pics i post them but that is not very likely but ill try
