I had one of the original ones way back in the 1990's, I let it die though. That same stock ended up 15 years later being this same plant.
I like them for contrast purposes only. And they are rather easy to grow, any fern/Buce, Anubias tend to be good money makers over time. New leaves on all plants have less chlorophyll, so the 1st 3-4 leaves tend to be very white.
They are not hard to grow. Pinto is a larger type of nana, it's not as white as these in submersed form. This is a whiter petite nana variety. Some virus wiped out some Asian growers, so now it's very rare over there.
The soil is new ADA AS, rich CO2, pack of SAE's and feeding often, there's not much plant biomass,so there's not much nutrient demand and the light is pretty low.
So I add some GH booster every once in 3-4 weeks, maybe some trace mix once a week if I remember, but they grow fine with rich or lean ferts, Anubias just do not have that much nutrient demand. And like all plants, the lower light means even less.
I'll sell off another 20-30 plants or so, then figure out what I'm going to do with them scape wise. I need to find a use for them in a scape at some point.I tried a few things, but the 120 gallon is too high light for ideal growth. The 70 was good, but they do best rooted in soil and there's no spot for them in there. Which leaves me to the 180 and that's not really got any decent spots as is either.
