If You're in to holding Snail races, You might enjoy working with F. splachnobryoides. :-)This is easily the slowest growing plant I've ever worked with. It makes Anubias nana petite look like Speed Racer. After several months with pressurized Co2, dosing, heavy weekly water changes, and strong LED lighting My spla. has formed several nice Hunter-green "pillows" to work with on my Mopani Wood.
