Is Hornwort a Good Plant for False Siamese Algae Eater (Stonelapping Minnow)?

Hornwort fits inside the water range normally used for False Siamese Algae Eater (Stonelapping Minnow). The shared window is about 20 to 27 °C, pH 6 to 7.5, and 2 to 15 dGH, which gives you enough room to aim for stable middle-ground conditions.

Flow is another friction point because Hornwort prefers gentle, low-flow water while False Siamese Algae Eater (Stonelapping Minnow) prefers strong, stream-style flow.

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

False Siamese Algae Eater (Stonelapping Minnow) does not put unusual pressure on this plant compared with harder fish-plant combinations.

Hornwort has high cover density, low uproot resistance, and delicate leaves. It can also help with surface cover, breaking up sight lines, shrimp refuge, fry refuge, and spawning sites.

The plant helps break up sight lines, which can soften territorial behaviour.

The limiting issue is the fish wants a very different current pattern than the plant prefers.

Hornwort is a stem plant usually used floating.

False Siamese Algae Eater (Stonelapping Minnow) is a cyprinid, so the pairing works best when the planting style supports how that fish uses space and cover.

In this pairing, the useful plant values are surface cover, line-of-sight breaks, shrimp refuge, fry refuge, and spawning sites. Place it where False Siamese Algae Eater (Stonelapping Minnow) 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: The fish wants a very different current pattern than the plant prefers.

Hornwort is usually the wrong plant for False Siamese Algae Eater (Stonelapping Minnow) 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.
