I lost five fish and three shrimp overnight in a nine hour period so I know how you feel. Everyone was looking good and eating when the lights went out at eleven, and by nine the next morning all those creatures were dead. Kicked it around on here and on Alberta Aquatica but never really came up with a solution. The only fish that lived is a firefish, and all shrimp died. Corals were all fine and so were hermits, snails, anemones, sea apples and an emerald crab.

I have since started to restock and have not run into any problems with my new fish or cleaner shrimp. Alive and well and healthy. I will let you know if we ever come up with the reason it happened.

Suggestions I received: Hitchhiker, oxygen issue, water quality issue or contaminant getting into the tank. We found some bristle worms but only small ones, oxygen issue would have taken out the corals and crabs too I believe, water quality was tested and appeared fine, and as for a contaminant I cannot think of anything that was sprayed near the tank.

Yours are dying slower so I think you can eliminate oxygen as an issue. Water quality I have heard corals and inverts feel it first. How about a hitchhiker? Even if you have not added any new live rock recently, some hitchhikers have to teach themselves to catch a fish and that takes time.

Really sorry for your loss.

What anemones do you have?

Mixing anemones is a dicey business. You get things like allelopathy and chemical warfare that isn't obvious but produces weird random things that leave you puzzled as to what's going on. Not always a problem, in fact, it's more often not a problem, but there's "potential."

In the case of some anemones, for example Heteractis magnifica there is potential for the anemone to cause massive tank death. Probably some kind of defense mechanism triggered in times of stress, but lethal in a closed system. I've had no fewer than 3, possibly 4 (I've lost count) lethal events where I've lost 100% of my fish due to the anemone being moved. (I didn't clue into what was happening at first.)

Well I'm happy to say all is well right now. the Angel was my last loss on Saturday. 40G water change on Saturday then another on Monday and I'll do another one tonight. I'm left with just my bigger fish although the Angel and the Black Leopard Wrasse were bigger fish as well.

Thanks for all the help. I'm hoping I never need to investigate further
