Is this normal?

My hairy mushroom settles in one spot for a week or two then decides to move. While my other mushrooms are as happy as can be, now he's riding on the back of my snail

Typically they dont move unless unhappy which would be due to too much light or what I believe is water flow.
They require moderate light and water flow along with a little iron and stronium in the water
