One submersed grown anubias barteri var. caladifolia "variegated king" (true Anubias VarKing), with rooted rhizome and 3-5 leaves.  This is one of the rarest anubias varieties, with specimens selling from $80 to $120+ online.  Because it was grown submersed, it does not need to transition from emersed to submersed growth form.  I grew the mother plant in soft water, under high light, with injected CO2 gas and water column fertilization.  However, it should also grow well without CO2, in medium hard water, and under low to medium light.
