Treat this as a managed pairing. Plant it securely, give it time to root or attach, and use other plants or hardscape if the fish needs more shelter than one species can provide.

The decision should center on this signal: Copper Harlequin Rasbora often benefits from floating cover, so this plant may need to be part of a mixed planting plan rather than the whole answer.

Madagascar Lace Plant can work with Copper Harlequin Rasbora, but only if you are honest about the pressure the fish puts on the layout.
