Croaking gourami tank mates
A small gourami at 7 cm that produces an audible croak during spawning. Needs a quiet planted tank with surface cover and easily startled by active communities.
Common mistakeRunning bright open-water lighting with no surface cover is how keepers invent permanently hidden croaking gouramis that refuse to spawn or display. They need shaded surface areas and softish water. Do not treat them as a high-flow showpiece for a bare nano.
