I am new to having live plants and try and be careful now after also making a few mistakes like buying a plant that only the roots are suppose to go into the water the leaves stay out. I wasn't told that when I bought it. My LFS has lots of plants but most of the clerks have no clue what they are. The local Petco is better and has a fish/plant expert but even he has given me wrong info. Best to do your own research first. Take a picture of the plant and research it on the net before buying.
