That does sound good. I saw 3 this morning so seems (somewhat surprisingly) that the yo yo loaches are leaving them alone. Will see how they go.
I keep meaning to spot treat with h2o2 so anything the snails can cut out will help. One was busy on a trek across the gravel and another was kind of waving on a plant with green spot algae that I have been also slack on treating. One side of the tank gets a little natural light and it seems this side gets a bit more algae.
Do you find they damage the plants much? Not that I'd probably notice with the fish but out of interest.
