whats your reasoning behind keeping the water level an inch or so low? so the snail doesnt get out?
There is no telling yet if Taylor's snail is a male or female. Males have penis sheath. In this case, they won't utilize the space above waterline to lay their eggs. Many snails met their deaths when they fell from tanks while looking for their spawning sites. It is advisable to leave 2 inches of space above waterline and cover the tank although there are some cases where the snails simply do not go astray outside the tanks.
