    Hello to all,

    I've had a torch coral in my tank now for approx 2 months and it appears to be doing well. I've seen it fully expand on an almost daily basis and the tentacles appear to be happily waving in the current. The flow is medium to strong where the coral is located.

    The coral is placed at the bottom of the tank and the closest neighbour to it is a small colony of mushrooms and button polyps which are approx 10 cm away ( Corals in my tank are : Mushrooms , GSP , Mycedium , Button polyps ) The pic below shows the placement of the coral in my tank.

    Over the last week though I have noticed the following happen to the coral :

    1. Whenever the main lights go off , the coral will retract it's tentacles and will not "open up" again until the next morning when the lights come on. The retraction of tentacles does not expose the skeleton , but the coral merely appears very "bunched up"

    2. I have seen some mesenterial filament being discharged from the coral . This occurs during the day time only and happens every 7-10 days. It is only a very thin single string of filament which is being released. I do not feed this coral , but it does "catch" some of the flakes which I feed my fish.

    Question : Would the release of mesenterial filaments constitute some form of chemical warfare or is it merely a response to feeding ?

    Any ideas as to why the torch coral closes at night ?

    1. 100% normal. Because they rely on photosynthesis.
    2. No it will not result in chemical warefare. IMO

    Thanks Mek ,

    Would the release of mesenterial filaments be a cause for concern though ?

    In my previous setups when that should occur, I noticed no ill effects to other corals or the coral itself. So I would say it is fine.

    1) 100% normal
    2) We all need to go at times, give the poor thing some privacy;)
