Is it just stress. I performed agressive water change after carpet anemone slimed everthing. I've had this clam since Nov 07, happy, healthy, so blue! She's under a 175W 10K lamp on 8 hours, dual actinic for dawn to dusk. SP 1.026 ph 8.3 no ammonia, no nitrite nitrates runnign around 20(I continue with this prob, I do water changes, I skim, I have DSB) phos .05 ca 400 mg 1300. I do need a new a new MH lam, which I have ordered an XM 15K 175W. She's lost a little color over the last two weeks sice my MH light has gone "yellow". But withdrawn mantle is new. Temps been warmer for month, never above 82, now running chiller for consistent 78. Feed REEF Nutrition Phtyo and DT. Shouldn't be hungry. Should I relax, let her acclimate to to new water, or is quick intervention needed. hope pix are helpful. Thanks, Chris

Looks very stressed right now i would let it sit for awhile, and make sure you get a new bulb in there soon, as the crocea really needs that strong lighting. Check why your nitrates are so high, are you running RO water? When you say you feed Phyto are you target feeding or just feeding your tank remember its not the best idea to target feed your clam you might block the gills. I wouldnt recomend moving it at all you will just stress it out more. As being a crocea they usually like to be on a rock structure in order to plant its foot, i couldnt tell if it was or not.

Thanks for your response. I didn't know about the target feeding being a problem, I'll lay off that. She's actually in the sand right now. Even when her mantle was fully spread out, she wouldn't put her foot down on any of our rock. She kept getting knocked over by crabs, fish, etc... seemed happy and safe in sand. I guess I'll leave her in the sand until she looks less stressed. thanks.

How is the clam now? It doesn't look like it will make it in the pic's. Crocea's should be up on the rocks, the color looks bleached to me.

What fish and inverts do you have?
How do you dose your additives?
