Hi. I have a 1 and a half year old mixed reef tank with a pair of clowns, yellow scopas tang, blue tang, sailfin tang, and 3 blue/green chromis. All fish had been with me for more than a year already.
However, just this week, all 3 of my Chromis died in the most sudden mind boggling way and all in different days.
When feeding or viewing the tank from top view, I always turn off the pump and WM (Vortech MP40). The first Chromis died while I was feeding Ocean Nutrition pellets. As I threw the pellets into the tank the Chromis suddenly thrashed around and just dropped dead to the sandbed all in a matter of seconds. i asked all my reefer friends and they couldn't give any explanation of what happened so we just ruled it out as a fish stroke or heart attack. The second Chromis died yesterday in a similar manner.
The third Chromis died just a while ago, and I can't really find anything anywhere on what might have caused it. As usual I turned off the pump and WM. This time, I fed frozen mysis shrimp holding the cube with tweezers and whooshing it around to melt it. Then suddenly the Chromis just thrashed around like having a seizure and fell dead onto the sandbed. This time I observed that its mouth was wide open as it died.
Can anyone enlighten me as to what and how these deaths happened? It's really mind boggling.
Pics of dead Chromis 1 and 3 attached. No signs of disease, sickness, cuts, or bruises.
Thanks!
