Can clownfish kill coral?

[daniella3d]

I decided that if this goes on much longer I am going to separate the duncan in 2 colonies so that at least I won't lose both. I have this duncan for a year or more and it never looked like that, even on acclimatation on the first day.

I will watch it for a few days and if it get worse I will split it.

Duncans can do this thing from time to time where they look really ****ed off and stay closed for weeks on end, then open up like nothing was ever wrong. Duncans are funny like that. And they're stupidly hardy... I doubt your clown could kill it unless it's getting to the point where it is doing actual damage to the flesh of the duncan.

I'd give it some time and see what happens... likely your clown is going to get bored of the duncan an move on.
