    Hi guys,

    I have had a hammer coral in my tank for about 8 months and it's been doing fine. For the last few days it hasn't opened propperly and when i checked it yesterday i noticed that on 2 of the 3 heads the tissue that grows over the coral skeleton has receded right back to the lip (if that makes sense). On the other head the tissue overlap is proberly 5mm. Checked my parameters last night and everything seems to be in order. My other corals are growing well. Any suggestions on anything i could have missed or anything else i should check?

    Medium to low flow (probably more medium than low).......it's been happy there for months. Could it suddenly decide it wants less flow and start receding?

    there are millions of factors that we try and think of, sometimes corals just do die, they are animals and if the colony gets sick, it can fade away. yes some live for hundreds of years but that in an ocean etc etc with the best reef in world looking after them.

    the remaining head can be fed mysis or brine with some HUFA's added. are you feeding them? maybe your tank is a little sterile when it comes to food for micorvores etc

    I have been feeding phytoplankon after lights out about once a week....but hace been a bit slack for the last little while in target feeding the hammer itself!
    Will start with that again tonight. See if i can do somthing before it gets too late.

    On that note....how late is too late?? The polyps themselves still look fine just not fully extending like they used to. Its just the tissue that has receded quite a lot......is it saveble??

    it sounds like it was used to getting food as well as photosynthesising and when the food stopped it battled to sustain.
    yes i think it should be fine, just start feeding him again, what fish do you stave>

    Without a pic its difficult to say , but the " white tissue is new growth , it builds up calcium and expands from there.
    The retracted hammer " tentacles is why your only seen it now...
    Could be that its just sulking now for some other reason or - how old are the lights ?

    When last you put in trace ellements - iodine strontium ect ?

    But ive often seen the white tissue on the ends of our frogspawn/hammers and torches... and they have all been fine.

    Thanks David i will get a photo tonight to show whats going on.

    The lights are about 8 months old. I don't dose iodine or strontium as i don't have test kits for them, but rely on regular water changes.

    When the clowns started hosting in it i kept a close eye to see if they did any damage. The hammer never showed any signs of stress with the clowns hosting.

    They on the other hand are now looking a little put out as thier surrogate nennie has decided to shun them.:(
