Well the ramshorns around here are pretty much all like that.,
My plants were some of the most healthiest around here too,
Unlike alot I've seen, mine got really hugh leaves, were very nice.
Had alot of people buy from me simple because of how healthy they were.
You have alot but not as many as I had nor what I've seen in others tanks around here That have lost their plants due to these guys.
Already since I've rid my tanks of the rams, My plants are starting to flourish again.
This is what I had,
Floating plants like watersprite Their preferred method was to start at the roots, once the plant starts to be affected by the root destruction they move to the leaves & finish it off.
