Dermogenys

Halfbeaks spend much of their time near the surface. Provide secure cover, calm companions and planted shelter around the edges while leaving feeding access. Avoid a layout that forces frightened fish into the glass or lets stronger surface feeders dominate every meal. Aquarium depth alone does not describe the usable space they need.

The White Wrestling offer is labelled cf. pusilla, the Malayan offer pusilla and Silver only Dermogenys sp. Keep those distinctions when checking water and social needs. Confirm which foods the actual fish accepts, especially if prepared food is part of your plan; a halfbeak label is not a guarantee of a dry-food diet, sexed pair or ready-made breeding group.
