ok, so my apple snail crawled out of my tank about 2 months ago and i couldn't find him. today i was cleaning off a shelf and i found him behind the books, thinking for sure he was probably dead...but when i picked him up he seemed oddly heavy. i placed him back in the tank, and somehow he had survived. wow... he is crawling around and just gind now, man..2 months out of water, simply amazing...
