I absolutely have no clue what has happened.
Yesterday around noon I did full parameter tests.... The only thing that was reading at all was 10ppm nitrates, which should still be just fine.
The fish were happy and swimming until we went to bed around 2:45 am, the tank lights were off but you could see the fish swimming still. I thought, hmmm maybe stressed cuz we were up late, but then the fact that EVERYTHING DIED takes me away from that conclusion. It was like they just froze dead.
Basically all of the fish died within 5 hours after us last seeing them. I do not know of anything else that could have happened so quickly besides a drink being spilled into the tank.
As of now the Duncan, Xenia, and Mushies are OK... The Zoanthids look great... Snails are still roaming the tank (slowly), and the conch is not moving, hes alive cuz his eyes are going in and out, but hes not moving around the tank.
I removed all of the fish and the shrimp immediately this morning. I took Half of the water out of the tank, and added 5 gallons back in. Tank is 2/3 full cuz I do not have enough to completely refill until tomorrow, but water is higher than all rocks and corals. I plan on siphoning all of the water out to the very bottom tomorrow, rinsing all the rocks off and then refilling the tank. Basically starting everything over again.
I highly believe that it is possible that someone may have dumped in a drink, as I had a lot of people here, a few who got pretty drunk. All close friends or friends of close friends... But people get dumb when the drink so "here fish have a drink" may have happened. If anyone thinks there may be a different factor lemme know so I can fix it, but I am absolutely mind boggled as to what else it could be.
I am sad today. Way to bring in the new year..
