I'm now up to 4-5 varieties, and all seem to be thriving, with the Coffeefola being the most challenging, the couple varieties of Nana, thriving, but being smaller, aren't as impressive, but I have large Hastofolia, and Congensis that are large impressive plants, so far none have required me to put fertilizer in the tanks, they thrive in tropical and cooler tanks, and are holding up to Cichlid, larger Barb, and Silver Dollar abuse... if you haven't tried an Anubias, I recommend them...
