Waterweed reaches about 80 cm tall by 4 cm wide and is usually rooted in substrate with inert substrate is fine. 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, line-of-sight breaks, fry refuge, grazing surfaces, and spawning sites. Place it where Betta (Siamese Fighting Fish) can actually use that structure instead of hiding the plant where it cannot do much.

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

The decision should center on this signal: Betta (Siamese Fighting Fish) often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.
