plastic plants are just fine. I think a lot of the people, or most of the people here have Plastic Plants. I do! Love 'em. Found that real plants bring in all sorts of nasty things into the tank. Some are harmless, but Snails are one of many creatures that come in with live plants. I think Plastic Plants are best, or The dracaena also known as Lucky Bamboo. I had it in my tank for a while, but I moved it out because I wanted to change the set up, now it is in my kitchen growing out of a Frog shaped Pot.
