    Hi guys I have been noticing recently that the tips of some of my sps frags appear to be sort of chewn off. There is no damage to the rest of the coral however and its not constant, some mornings I will wake up and notice the growth tips of a coral are chewed away. Maybe once a week or something. Any ideas what it could be?

    What livestock do you have that you think would be eating it?

    I have two angels. One is an Eibli and the other is an emporer but they dont pick at the corals im 100% sure of that. I did spot a crab in the tank...i am starting to suspect that to be the one responsible

    Uhm well they certainly look as though they could be responsible. Big and chunky pincers

    More of the thumb and Index type, not sharp at all from what I had see. Also it appears that they cannot close completely

    Then he is a black emerald crab and not your culprit. What are your water perameters?

    Also I dont do water changes, I know that may be frowned upon but I supplement with the entire aqua vitro range. I dont have the time to do water changes on two tanks with university:-(

    Im not sure of the exact value. I last checked it last week but I remember thinking I need to fix my kh and get a better test kit for it. Im using a red sea kit at the moment and the colour was lower than the colour for normal

    Nope not burnt tips. Wouldnt the tips of all corals be burned in that case? Last week my little bali tricolour piece had a few growth tips damaged and then last night was this stag

    Things change so quickly it would be good for up to date set of tests
