I've never had much luck with regular house plants, so when I started adding live plants not too long ago to my crestie's tank, I didn't actually expect them to live. So imagine my surprise when not only did they live, but they are growing really well!
When I first added these she took a nose dive into the dirt when she tried to jump on this particular plant. Now it is big enough and has enough root structure to support her weight jumping and climbing on it. These two (same type) are about 4 inches from the top of the tank (it's a 29g). How do I "prune" these plants without killing them? Is there anyway to prune it and replant the parts so they grow more plants (excuse my naive questions - I have never kept so much as a garden...)?
The little dead end of the leaf in this picture has been there awhile (and thankfully not spread). Do I break it off or leave it?
