VerdictGOOD

Often a workable match in a suitable, well-run tank. Still verify behaviour in your setup.

Different swim zones and no temperament conflict. Bristlenose work the hardscape and substrate, denisons cruise the upper run. The 250L+ tank denisons need leaves plenty of room for a bristlenose to hold its cave.
