No such plant as far as I know. There's A. barteri v. nana which is your average Anubias, and there's A. frazieri which I'd say is one of your more delicate of the Anubias. So I can't see why they would recommend frazieri over other Anubias. A. coffeefolia is probably one of the toughest of the group. A. barteri is a standard that you always find in the fish stores and is pretty tough. Another genus to try is Crinum (thaianum or calamastratum), but you have to fertilize the substrate for these plants. Some people have success with plants in their African Cichlid tanks and some don't. It's all fish personality, I suppose, or maybe the fish needs to be raised with plants so that it sees them as part of the decor instead of as a snack. I don't know because I don't keep African Cichlids. $6/plant is not really expensive for a small Anubias in the stores.
