I mixed up a batch of frozen food with some Selcon and refroze it. My client fed it for 6 days and on day 7 all the fish died overnight, with the exception of the pair of perculas, their bubble-tip anemone, crabs, snails, and mushrooms. This was a well established 120 with a large Naso, Koran, Yellow tang, and various smaller fish, all of them inhabitants for many years. The dead fish were bloated, so I cut them open, expecting to find a gut-full of food. Instead their air bladders were full of air. Puzzling is that the clowns did not die, and do not even appear stressed. One (of 4) 96W PC bulb blew a ballast, but the anemone looks healthy, no loss of xoozanth.
They say nothing was spilled into the tank.
I have been servicing tanks for 25 years and never saw anything like this.
When I pulled out the dead fish the pH was 7.9. It usually runs 8.3 in this tank. The nitrite was 0.8 then down to 0.3 the next day. The ammonia remains 0. Filtration is a wet dry and tunze skimmer.
Can an anemone poison a tank with out dying?
Could the Selcon have done this?
Please, any thoughts on what caused this wipe-out?
Thanks
