missing dartfish/chromis

Hi all,

I'm becoming slightly concerned as to what's going on with my tank. She's been up and running for about 3 months and everything is going very well. I have a yellow tang, coral beauty, clownfish, yellow watchman goby and my CUC. I had a few blue green reef chromis and a beautiful dartfish.

All of the chromis have randomly disappeared over the course of a few days and now the dartfish has as well. The chromis were in the tank at least a week and seemed to be doing well, but slowly started disappearing. The dartfish was in at least a good month, but is now missing. My parameters all check out very well. Nitrites, ammonia, and nitrates all 0. Ph stable and I do water changes frequently. Phosphates read 0 and I use RO water. I've kept salt tanks for some time so I know I'm doing things correctly. Its a 75 gallon with live rock.

I've checked all over at night and have not observed any predator hitchhikers such as a mantis. I've checked my filters through and through and moved the rock around. They didn't jump out that I can tell... its freaking ODD!!! Sorry for the book, just looking for help/suggestions. Thanks

 

I looked a bit harder and found the dartfish shriveled up on the floor behind the tank Thought I had it sealed up pretty well, but still found a way to jump out.

As for the chromis, they remain a mystery. Ah well...

 

set a bottle trap and see if you get a hitchhicker I had my tank for months before I caught a mantis shrimb in my tank. sorry to hear about your dart fish, and hope you find your chromis.
