Snail by Piggy50 posted Jul 10, 2017 at 3:40 PM my snail is almost always at the top of my tank. Why? He's in the corner if you can't see him.
Mine does it all the time. It seems like he moves around a lot in the tank and then comes up to restart the top.
Some snails do like to climb to the top, but if they constantly stay up top it can be a sign of bad water quality.
