I have a new 40 gallon breeder tank that I stocked with fish two weeks ago. I added 6 gold mystery snails 2 days ago because the water parameters were normal again. It is heavily planted with duck weed, hornwort, java moss, java fern and amazon sword. After 8 hrs or so I check in on the tank and 3 leaves on a sword are destroyed, and many holes on the java ferns. I have seen all the snails eating the plants and I knock them off whenever i see it. I thought mystery snails didn’t eat live plants, how do i get them to stop?
