Can African Water Fern and Pelia Grow Together?

African Water Fern and Pelia share a workable water window around 20 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.

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

Flow needs deliberate placement because African Water Fern prefers strong, stream-style flow and Pelia prefers gentle, low-flow water.

Their light and CO2 needs are close enough for one routine: African Water Fern does best with low light and no added CO2, while Pelia 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.

African Water Fern reaches about 40 cm tall by 25 cm wide, while Pelia reaches about 5 cm tall by 15 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.

Both are typically attached / wedged to hardscape with no substrate required and feed mainly as water column feeders. The method is simple, but it also means the same planting zone can feel crowded if they are placed too close together.

Mature size is not the main thing working against this pairing, so normal maintenance is usually enough to keep the scape readable.

African Water Fern brings slow growth, low maintenance, and beginner difficulty. Pelia brings moderate growth, low maintenance, and beginner difficulty. If one grows much faster, trim that plant before it starts making the other look like the problem.

The main watch-out is that both plants tend to work in the midground and attached to hardscape, so spacing matters more than usual.

The strongest reasons to try the mix are that they share a workable temperature window around 20 to 28 °C; and that their light demands are close enough that one lighting plan can suit both.

Skip this pairing for most display tanks unless you have a specific reason to experiment. A better long-term choice is a partner plant that shares the same water window and asks for less compromise in light, flow, or maintenance.

Before trying it, solve the blocker first: One wants a gentle flow while the other is happier with much stronger movement.
