Water type is a serious mismatch: Watermeal is listed for freshwater, while Blue Back Blue Eye is listed for brackish water.

Blue Back Blue Eye does not put unusual pressure on this plant compared with harder fish-plant combinations.

Watermeal has high cover density, low uproot resistance, and delicate leaves. It can also help with surface cover and grazing surfaces.

Watermeal brings useful structure to the tank instead of serving only as decoration.

The limiting issue is they are adapted to different water types.

Watermeal is a floating plant usually used floating.

Blue Back Blue Eye is a rainbowfish, so the pairing works best when the planting style supports how that fish uses space and cover.

Watermeal reaches about 0.1 cm tall by 0.1 cm wide and is usually free-floating 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 surface cover and grazing surfaces. Place it where Blue Back Blue Eye can actually use that structure instead of hiding the plant where it cannot do much.

For most keepers, a tougher or better-matched plant is the smarter choice. If you still try it, test with a small amount first and be ready to move the plant before it is badly damaged.

The decision should center on this signal: They are adapted to different water types.

Watermeal is usually the wrong plant for Blue Back Blue Eye if your goal is a stable display tank. The issue is rarely one dramatic failure on day one; it is the steady mismatch between what the fish does in the scape and what the plant needs to stay attractive long term.
