Are These All Ramshorns?

[trojannemo]

hey guys. i know very little about ramshorns snails other than if it looks like a ramshorn, i call it a ramshorn.
but i wonder if these are all the same species or actuall different species:

these have all be caught wild when dipnetting. i have several of the brown/white variety, but only one of the all-white, and only one of the red/brown varieties.

are these all "giant ramshorns"? or different species? i want to know because i know giant ramshorns will eat my plants, but dont know if there are other varieties that wont?

thanks
