Overview

The sharpnose chocolate gourami is a peaceful, retiring gourami for a dim blackwater tank. It is a fish for experienced keepers.

Did you know

In the sharpnose chocolate gourami, the father does the mouthbrooding. Its relative, the crossband chocolate gourami, leaves the brooding to the female.

Caring for the sharpnose chocolate gourami

Keep a group of sharpnose chocolate gouramis in a blackwater tank of at least 24 gal (90 L). Give them plenty of leaf litter and dim light.

Keep the water very soft and acidic, at 72 to 79°F (22 to 26°C) and a pH of 4.0 to 6.5. They prefer slightly cooler water than most blackwater fish, so avoid high temperatures. Feed small live and frozen foods such as baby brine shrimp, daphnia and bloodworm. They are fussy micropredators that often refuse dried food.

Keep them in a quiet species tank or with very calm tank mates. The sharpnose chocolate gourami is a paternal mouthbrooder, and the male carries the eggs and fry in his mouth. Breeding them is hard.

Good to know

Sphaerichthys acrostoma is a member of the family Osphronemidae and the biggest of the chocolate gouramis. Its pointed, elongated snout and larger size set it apart from the other Sphaerichthys species.

In the wild

The sharpnose chocolate gourami comes from soft, acidic, tannin-stained blackwater in the Mentaya River drainage of Central Kalimantan, Borneo. It lives among cover in shaded forest waters, keeping to leaf litter and submerged wood in dim conditions. The water is mineral-poor and often cooler than most tropical blackwater.
