Riccia is a beautiful plant, but I need something that can handle less than
optimum lighting and no CO2 injection. IIRC anubias has a rep. for being
hardy, and it looks good. I'll try that.
Anubias are hardy plants that do well in low light. Many of them are short, so
they would be a good choice for your small tank. (There are also tall
varieties, that make good showpieces.)
Since they are slow-growing, you might want to put them in a shady area of your
tank. Otherwise, spot algae grows on its leaves.
