2 for 1! You get both Hydrocotyle sp. 'Japan' and Brazillian pennywort. These are pretty easy plants to keep and will quickly grow out of and around your tank. The Japan variety has tiny leaves that look great in a nano tank, while the Brazillian pennywort is a fast grower and a great nitrate remover.

I'm going to try these in my outdoor tubs this year, they have fine roots and should make good hiding places for fry.
