I have a giant mexican turbo snail, easily 3 years in the 340 gallon display. Recently, I don't know if it's because of old age or a fish or a shrimp, but, he lands upside down in the exact same spot in a high traffic tunnel. I flipped him right side up and the next day he was upside down in the same spot. I finally moved him out of that spot closer to a rock and flipped him over, now he's all over the tank. I'm curious if he wanted to clean the bottom of the rocks of the tunnel and fish kept running into him and knocking him down or his grip wasn't strong enough and he just kept falling. Or decrepid snail at his old age?
Then, I had a green blasto that I had glued down and it was doing great. I had just observed it after cleaning the tank. Coincidently the same time I got the snail doing o.k. my blasto frag completely disappeared. Not sure if the glue released or someone nudged it enough to knock it into the sand bed. Init's place are three leather corals taking off. I have eliminated all my fish that like to snag and bury corals. The only shrimp I have is a harlequin.
