Clam troubles

[silentcivilian]

**sigh** Ill come clean, I may have possibly influcened this via a private message..

Wont name drop, but picked up a new clam off a fellow reefer.. well established 8" Squamosa.. here is the story (hums fresh prince while typing)

Time for story by picture...

Go to get clam at a gas station in NW, I meet him for pick up, put it into heatbox in car as its -40'c outside, at styrafoam box with heatpacks.. get home, check it, slightly pulled back, put lid on, put in tank floating to acclimate water..



acclimating and slowly adding water to get it used to my parameters... left lid on so I wouldnt shock it..



once lights are out, put it in tank, has no negative reactions (about 1.5hours in bucket).. check 2 hours later, still fine.. go to bed. Wake up.. look at it, still fine maybe even showing signs of returning to full extension.. go to work for 12 hours.. come home to this..



very very retracted into shell..

stuff spewing out the back...



its really pulled back and I can see stuff in its mouth up front that doesnt look happy.. checked parameters.. everything looks to be in check.. nothing else in the tank seems affected.. all the zoas are good, leathers are good with good polyp extension, sps is fine, frogspawn is happy and hammer is happy..
two more macro pictures..



mouth and its ejecting its intake of food which I understand is a shock reaction.. similar to some eating disorders humans suffer..



im new to clams but read alot.. I know its not supposed to go that far passed the mantel or its under lying tissue..

SOOOOO... checked tank, no param problems to be heard of..
Flow good..
Problem noted approx 12 hours after last known goodtime.. aka put in tank after purchase from another member..
Secretly watched fish from distance.. no one nipping or even going near it for that case..
Crabs only stay on the rock unless they fall.. I apparently bought the allergic to sand crabs.. its true, there is a grave yard to one side of tank of preworn shells..
Turned off daylight lamps and left only acitnic lights on incase this just light shock..

anything else you may know there fellow Clam gurus..



What do I do if anything!!
