Wondering where I can get more of these. I had about 4 plants, but only one survived and the one that is growing now is huge! I've only had it for about 3 months. I do want to get more, but don't know which site would be the safest. The site that I ordered a plant package from gave me snail eggs and my tank got infested for a long time. I'm trying to avoid that situation as much as I can. (I know, I know, probably should have thoroughly cleaned off my plants...) Anyone know a good site?
