I recently got a snail for my crayfish tank because I can't keep up with the algae and my crayfish is also having an issue with keeping clean she has a lot of algae on her I looked over and the snail is literally on top of my crayfish and my crayfish is chilling doesn't even care which is very shocking cuz she's usually very combative and she's alive so I don't even know what to think here's a photo has this happened to anyone else?
