I have never put plants in my tanks all of the years I have had fish. So I know nothing about them. In my 90 gallon tank I have caves, tank gravel, and fake plants. I noticed that my Kissing Gourami and my dwarf gourami sometime peck at the fake plants. I would like to get a plant that they can munch on but don't have a clue when it comes to plants. Any help?
