So.. I've never had much of a green thumb, but today I was at my local petstore, looking at bettas.. (of course!) and I ended up with a new guy who was begging me to take him home.. and the guy there was going through the tank of live plants which was pretty well ransacked due to a recent sale, and he picked out 3 plants and said he would throw them if for free if i wanted them, as they were just going to throw them out anyway.. so, now I have a new fish (pics coming soon) and 3 plants that I have no idea what to do with.. anyone have any tips about live plants?
