Rotala sp. ‘Araguaia’

December 16th, 2008

Rotala sp. ‘Araguaia’ is one of the plants that my wife brought back for me from Aqua Forest Aquarium in San Francisco, CA.

Rotala sp. 'Araguaia'

It’s one of the nicest new plants I’ve seen enter the hobby in a long time, as it has an oblong leaf shape that turns a pumpkin orange color. In addition, it branches readily, creating a nice bushy effect without too much effort. I haven’t found this plant to be very demanding at all.

It grew in my wormstrate substrate without any additional dosing, besides CO2, but definitely grows faster and a little bit larger in my 50G with high light, CO2, and added fertilizers. I got good coloration in both conditions.

Unlike species like Rotala sp. ‘Green Narrow’, this variety grows vertically, which provides a nice contrast to the aforementioned plant.

Right now, the source of this plant is unknown, despite being named as Araguaia.’We’re in the process of trying to flower and ID it properly, but that can be a long and laborious process.

All in all, I don’t have any complaints about Rotala sp. ‘Araguaia’. Therefore, I can recommend this plant to most people as something different from the more common Rotala rotundifolia. Currently, most stores in the U.S. don’t have it, but it’s available online from hobbyists on sites like
