My tank has been running without any issues for nearly a year and a half.  I've not had any disease at all.

About two weeks ago, I added 8 Allen's damsels, a Yellow tang and a Gold Ring Bristletooth.  They've all been fine, no sign of disease.  Yesterday I noticed one damsel was missing.  I found the body later.  I couldn't see anything wrong with it, so I put it down to the stress of the move.  I found another body today, and can only count 5, so missing one more too I think.  No visual clues from what I can tell.

Is there a disease that affect damsels I should know about? 
Any ideas?

Mike

Were they the smallest of the damsels? They're almost the same as Chromis, and it's common to lose a couple of Chromis not long after introduction...


I wouldn't worry unless it's the bigger of the bunch that are popping their clogs.

Large one today, small one yesterday.  Not sure what's missing, as they were all different sizes.

So, I lost one more, then had 3 for several weeks, then lost another.  I now have just two left  :(

Still no clue, other than bullying within the group, what it could be.  No signs of stress, disease, etc. 

I've also lost my Royal Gramma, which I think may have been stressed by the damsels.  It seemed to be the boss, with it snapping at them on the odd occassion (when they came too close to it's cave), more than the other way around, but I figured it was just teritorial and would work itself out.

Not sure whether to try adding more damsels to top up the numbers, or just accept defeat.

Were they feeding ok?
obviously your levels are ok!
it sounds like exaustion or something (a hitchhiker)is picking them off when they're resting at night, there can't be any poison\toxins in the water because all fish would be effected.
I should really sort this out!!

Yes, they were feeding fine.
Levels are all good.
Mike has heard of them fighting amongst themselves and picking each other off, so it could just be that, hence me being unsure about topping up the numbers, just to have them kill each other again.
It could be a hitchhiker, but it's been 18 months now, and I've not seen anything dangerous, and nothing has bothered my madarin, or my goby (although I've only had him a week or two) who both sleep on the sand.  The goby disapears under the rock at night, like the damsels too.
It's an odd one.

I'm thinking of just leaving the damsels now, and may look back at the anthias I wanted.

Probably for the best, it's a shame though.
