Hello all, I currently have 2 tanks, a 20 and 5 gallon. They both have live plants, but after about a year of having live plants not doing too good I'm debating on switching to silk. My question is, do snails do ok with silk plants? Like if they get algae on them, can they even scrub the algae off to eat it? If they cant then I will just leave them as is, but figured I'd ask!
