C. walkeri var. lutea
C. crispatula var. balansae
and I think C. nurii? maybe wendtii? I need to get an ID on this guy, the LFS doesn't exactly label their plants all that well.
The tank I keep them in is here: my 30 gal
They are all grown submersed. I have had the lutea for about 5 years and it is the king of the tank
