The image above shows the three ‘larger’ varieties of Tonina fluviatilis, with classis T. fluviatilis in the top of the image and rear of the tank, Tf “lotus blossom” in the left center and Tf “narrow leaf” in the bottom right. The lotus blossom variety is one of the most distinct strains with really stiff upright stems but the classic and narrow leaf varieties of T. fluviatilis appear more similar with more ‘slack’ stems, leaves that eventually turn downwards and more vertical growing potential. Although some strains of Tonina, Syngonanthus and Eriocaulons can have really subtle differences that tell them apart, it is easy to see why Tf “Narrow Leaf” is called that, with it’s much more slender leaves that make it look almost reminiscent of Syngonanthus caulescens. This is one of my favorite new varieties of Tonina style plants and it is sure to become a popular plant in the hobby once it spreads beyond just a handful of aquarists that are currently keeping it in the U.S. One more pic after the break.
