I bought some Wisteria for my aquarium a few weeks ago, and it is doing great! I love the rate that it grows and I love the vibrant green that the plant displays! When I had gotten the plant, the leaves were small and round. As time has progressed, the leaves have come to closely resemble that of the Wendlov Java Fern that I have in the tank. Is this a normal look for the Water Wisteria, or is the plant beginning to display new traits?
