sorry to hear about your loss man. May be its where you are buying them from could or may have a impact on your livestock. But with me when i had my 62 gal sps all topped out going really good my cucumber decided to take the powerhead express and lick the side of the maxi jet.. Well i came home from work around 3pm in the afternoon.
And my 4 yr old coral beauty was dead in the corner floating there with its mouth open.
It looked like the fish was scared to death it was the only fish that didnt make it weird thou. may be it was spooked from the cuke dying. I know when i got home the cuke was still living because i had to cut him off he was mangled...
So i was kinda in shockness. I did a 20 gal water chanege and everything was good after that .....
go figure.
