Anyone know of any nice small crypt species that wont grow taller than 5inches?
C. parva stays very small, but also grows very, very slowly. C. willisii stays smaller than 3in in the well-lit areas in my tank, could be a good choice as well.
Dwarf Sags are nice, but tend to run around in the tank a lot. Can be difficult to keep them out of similar carpet plants.
Check out Blyxa japonica, it grows a bit taller, but looks really nice and is easy to keep under control.
