    Most of the times the Black Spots are stressed related..I believe it's relatively easy to "cure", but the majority leave their Fish as they believe you actually cause more stress with removing them, then QT and then back again...Both my Clowns have Black Spots...I'm suprised that when I woke up this morning their spots haven't increased as I had no power for 10h and stirred with a spoon every 15min...I would have thought THAT would stress them out....:p Post a pic so we can confirm that it is indeed just "plain" black spots and not something more serious....hmmmm think someone said that if you have snails in a Tank that would explain maybe the "origin" of Blackspots in you'r Tank...

    Just one of many Sites...
    Did you Test you'r water after the water change...? maybe NSW had higher/lower Salinity and/or MAG,ALK...maybe even not "clean" enough...?

    What does Hosting against something mean , like as it would with an anenome ? they sit up against the glass on the one side and thats it , must i just leave them? and it will go away...do u think maybe it was the water change? All my parameters are fine...

    Zoanthids are quite capable of inflicting the damage. Ive seen many a clown trying to host them

    Oh serious rakabos excuse my ignorance :p I never thought they would sting a clown , ok I learnt something today , well i added the zoanthids on the week end they come from the beach in Chakas Rock , so that could be an option, so will the rash go away then do you think ? here is one of 3 rocks with Zoanthids on. they are not opened here but they do open up nicely

    Run a google search and you will see how common it is, just make sure that the examples you see, match what you see on your guys

    The black spots we are referring to is called hypermelanisation and - as mentioned in this thread - is a common response to the stinging cells (nematocysts) when they begin hosting/habituating a new coral. It should fade as the host become more acclimatised to their presence.

    That said, yours does not look anything like the hypermelanisation that my clowns get. As Dave mentioned, the black spots are usually far more discrete and clear, and doesnt usually cover the whole body... I'm not sure what that might be - but an extreme hypermelanisation is possible, especially seeing as you just introduced corals. Although zoas are not a particularly common host for clowns....

    I'd remain observant, and as Rakabos suggested a widespread google image search and trying to match up yours with others may be your best bet.
