Snails on parade

[Lonkley]

I don't really think it's important, but why do my pest snails flee my waterline. Sometimes there's none, sometimes there's like 30 (not all by any means).  Is it normal? 

The fish are happy. The amano are happy. The plants are thriving.  It's an aquaclear 50 and a sponge for redundancy. Ph is about 7. Ammonia 0, nitrite 0, nitrate about 20. Hard water.  No CO2.

Do you think the snails are getting enough food? If the tank is pretty clean they might just be hungry and looking for another place to chow down? 

[Lonkley]

There are some dead leaves and small amounts of green algae on the sides. Kind of impossible to figure out biofilm but I presume there is food. That said, I have a fat otocinclus,2 mystery snails and 10 amano. They did strip most of the green algae.

 

Also, they aren't trying to leave the tank. It's like they sleep there

My pond snails do that too. Idk why because half would always be above the water line and the other half would be in the tank foraging for food.

That's what I'm seeing.

Mine do that too. The pest and the ramshorns. It made it easy to crunch up the pest ones for my fish. They do seem to like algae wafers and repashy.

If you have hard water and it's evaporated down enough, there are likely mineral deposits on the glass that they are eating. Mine will do this too and I have hard water.
