i have recently bought three ramshorns snails and now my amazon sword,dwarf hairgrass are all being eaten!first the hairgrass is getting ripped out and eaten then my amazon sword has pieces of leaves missing and some bulbs i bought at walmart they finally rooted and sprouted some leaves and they were munched away the roots that is.now the only reason im saying its the darn ramshorn is all this happened after i added them.I thought they didn't eat live plants and i feed them every day unless i forget but when i do i feed them 2 huge cucumber slices.i do have 4 briggs a handful of MTS and of course 3 rams.is two slices not enough for them all?
