What live plants are safe for my aquarium fish?

This is a great question.I only have fake plants because I was so scared to get live plants because I heard they could kill my fish and cause infecions.

i use this store to help me with 'safe' plants to buy: http://www.aquariumplants.com/herbivorou... 'hornwort' is not on that list, but i do know that my goldfish and plecos do not eat it. and i grows like hell. * if you do end up buying a plant that your fish like to nibble on, you can deter them from eating that plant by adding cabbage, lettuce leaves every now and them. give your plecos cucumber... **also, if the plant is aquatic, and bought from an aquarium plant dealer, it probably wont hurt your fish.
