    Hi all,

    My one clam has started gaping its intake really really wide, should I be worried as I have heard they usually do that when they start dying, he still responds when i poke him and closes up but opens again with a really wide gape. He's fairly large and in a bit of a cramped spot, is he dying or just trying to get more space? I would try to move him but i think he's attached via the byssal strings.

    All parameters are in check and have thriving SPS and the clam next to him is growing fast so I can't see why he's gaping.

    Thanks

    Gaping is not a good sign. Post a pic of it.

    Gaping clam with a retracted mantle is a very bad sign,. Try posting a pic for better diagnosis.

    if the mantle is all the way extended, that is less of a worry, a happy clam has his (or her) mantle extended, The inlet/mouth should be open and defined in its edges. The outlet siphon should be extended. Move your hand over the clam, does it close quickly, what does it look like at night, is the mantle retracted slightly, is the edges of the mantle smooth (they shouldn't look like gathered "pastry")?

    But a pic will help more.

    a clam rarely recovers once it goes down hill. You will notice the mantle receding more and more. If it does then it is over and you should remove. Is it still reacting or has it stopped? Remember that clams can starve in ultra low nutrient systems but it takes some time for it to die. What lights are you running? Have you checked for snails at the base of the clam?

    Light is sufficient in my opinion. Does it react if you move your hand over the lightin any way. Also if you lightly touch the mantle does it react at all? If it does is it a slow reaction or quick.

    gonna check tomoro for response, also gonna check for snails.
    It can't be an imbalance of waterchemistry because sps are thriving

    Good luck. Does anything touch the mantle when it is extended. i had an elegance sting a clam to death. Even a leather can irritate it.
