Dead Snail

[mllrtime33]

My turbo snails like to hang out around the top of the tank. When I did a water change the other day, one was out of the water for about 15 minutes before he detached and fell to the bottom of the tank. It died a day or two later. Is it okay for snails to be out of the water during a water change? Could this be why it died? I'm testing 0 ammonia and nitrite and 0-5 ppm nitrate.

I'm also starting to notice what I think is cyanobacteria in the tank. It's particularly heavy in the area where the snail died. Could that have something to do with it?

Exact thing thing happened to me the snail was sitting right on top of the rock, didn't notice him, he was out for about 10 minutes and by the time I had noticed him he was dead, going to have to be more careful from now on
