Is Glosso a Good Plant for Blue Back Blue Eye?

Glosso and Blue Back Blue Eye do not share a clean environmental window, so the pairing is already under pressure before behaviour is even considered.

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

Water type is a serious mismatch: Glosso 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.

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

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

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

Glosso is a stolon / runner plant usually used foreground and carpeting.

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

Glosso reaches about 3 cm tall by 15 cm wide and is usually rooted in substrate with nutrient-rich substrate preferred. 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 grazing surfaces and shrimp refuge. 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.

Glosso 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.
