I don't have good beginning for this story because I don't know what's what's going on. On May 19th everyone was fine. On May 20th my Yellow Tang vanished. On May 21st my Power Brown tank was fine and on May 22nd he/she was gone. Both fish have been in the display tank for 7 months. Before that @Jay Hemdal and I went around (while both fish were in QT) trying to figure out what was up with the Yellow Tangs breathing. That never led to anything conclusive and since then both fish where fine. I haven't added any fish to the system for 6 months, but I have added coral fags here and there. My parameters and ICP results are all green (I'll post them here somewhere). So my question is, if the fish show no signs of disease and no signs of stress how do they just disappear in a 12 to 24 hour period of time? I've lost fish in the past, but I usually have a body to dispose of. In this case they're just gone. The tanks have screen tops, so jumping isn't really an option without leaving some evidence that the screen moved.
Am I looking for a predator? And if so what could completely consume a 6" tang in 12 hours? I am using my original Fiji live rock, but it sat dry for 10 years and was cleaned before I restarted the tanks. I know that nature will find a way, but really?
The other fish ( 2 azure blue damsel's, 2 captative bred clowns, and a Coral Beauty) are fine, as are the White tail tang, Rock Beauty Angel, purple fire fish, and Porcupine Puffer in the FOWL half of the system that shares the same water system.
What am I looking for an how do I find it?
