Both do best with moderate flow, so circulation does not need to be split into competing zones.

Both are suited to freshwater, so salinity does not add an extra planning problem.

Congo Puffer (Potato Puffer) does not put unusual pressure on this plant compared with harder fish-plant combinations.

Crepidomanes Fern has low cover density, moderate uproot resistance, and delicate leaves. It can also help with shrimp refuge and grazing surfaces.

Its structure adds useful refuge value beyond the normal visual role of the plant.

There is no special plant-pressure warning here, so solid anchoring and stable husbandry matter more than unusual protection.

Crepidomanes Fern is a rhizome / epiphyte plant usually used attached to hardscape, foreground, and midground.

Congo Puffer (Potato Puffer) is a puffer, so the pairing works best when the planting style supports how that fish uses space and cover.

Crepidomanes Fern reaches about 15 cm tall by 20 cm wide and is usually attached / wedged to hardscape with no substrate required. That makes placement and anchoring more important than simply adding a larger bunch of stems or leaves.

In this pairing, the useful plant values are shrimp refuge and grazing surfaces. Place it where Congo Puffer (Potato Puffer) can actually use that structure instead of hiding the plant where it cannot do much.

This is a sensible planted-tank choice for Congo Puffer (Potato Puffer), especially when you want the plant to do real work as cover, sight-line structure, or habitat detail.

The decision should center on layout quality: keep the plant in the zone where Congo Puffer (Potato Puffer) actually swims, shelters, or uses cover.
