Anubias barteri var. caladiifolia "1705" is an adaptive and sturdy plants available. It accepts almost any water quality from soft to hard and from acid to weakly basic water. It is very slow growing like any other Anubias species and therefore the leaves are quite exposed and likely to develop a cover of epiphytic algae by age. This is less likely to happen if it is grown in soft and slightly acid water where less inorganic carbon are available for the production of epiphytes. If problems with epiphytes occur you may then try to cut off the CO2 enrichment as the carbon requirements of Anubias is very low due to the slow growth, and the epiphytes are most likely to decline after a while.
Compared to Anubias barteri var. nana the leaves of Anubias barteri var. caladiifolia "1705" are slightly more rounded but also larger. It is also slightly sensitive to transport and environmental changes than Anubias barteri var. nana. None of the Anubias species like to have their rhizomes buried in the substrate and the growth is actually most successful if the plants are fixed to rocks, roots or other material of decoration and it provides very nice ornamental effects.
