This is for a chunk (handful) of Pennywort . This is the plant that you may have seen floating in my 75 gallon tetra tank in the garage. Great floating plant and way to create top cover for you tanks. You can also break it up and plant and floating it. Lots of possibilities! Easy to keep which means it tolerates most all conditions even high temps. Just make sure if you float it to let if have a spot out of current so it can rest up top.
