Can Afzel's Anubias and Crepidomanes Fern Grow Together?

Afzel's Anubias and Crepidomanes Fern share a workable water window around 22 to 26 °C, pH 6 to 7.5, and 2 to 10 dGH.

Both plants are comfortable in freshwater, so salinity is not a meaningful obstacle.

Both prefer moderate flow, so circulation can be planned as one steady pattern.

Their light and CO2 needs are close enough for one routine: Afzel's Anubias does best with low light and no added CO2, while Crepidomanes Fern does best with low light and optional added CO2.

Both plants naturally lean toward the midground and attached to hardscape, which is why spacing, pruning, and final mature size matter more than they do in a more staggered planting mix.

Afzel's Anubias reaches about 35 cm tall by 25 cm wide, while Crepidomanes Fern reaches about 15 cm tall by 20 cm wide. Use those mature sizes for the layout, not the small nursery portions you bring home.

Shade is not the main concern here, which makes the layout easier to keep balanced over time.

Afzel's Anubias is typically roots anchored, rhizome exposed with no substrate required and feeds mainly as a water column feeder. Crepidomanes Fern is typically attached / wedged to hardscape with no substrate required and feeds mainly as a water column feeder. That difference can make the pairing easier to arrange than two plants fighting for the exact same root or attachment zone.

They can share the space, but the scape will stay cleaner if you leave more room than the labels alone might suggest.

Afzel's Anubias brings slow growth, low maintenance, and beginner difficulty. Crepidomanes Fern brings slow growth, low maintenance, and advanced difficulty. If one grows much faster, trim that plant before it starts making the other look like the problem.

The practical watch-outs are that both plants tend to work in the midground and attached to hardscape, so spacing matters more than usual; and that you will want to leave more room than usual for mature spread and routine thinning.

The strongest reasons to try the mix are that they share a workable temperature window around 22 to 26 °C; and that their flow preferences sit close enough to tune one layout around both plants.

Use this pairing when you want two plants that can share one routine without forcing a compromise at every step. It is strongest in tanks where mature spacing is planned before the plants fill in.

The simple success test is whether both plants still look healthy after the faster grower has been trimmed several times. If one keeps declining after routine care, the layout is probably asking too much of it.
