Apistogramma eunotus

Apistogramma eunotus is a species described from the Ucayali near Pucallpa in Peru, ranging from there east to the Japurá basin in Colombia and Brazil. The large bluish spot on the male's gill cover and the crescent-shaped dark mark at the tail base are the best identifying features. Typical males have a plain, rounded tail; in some local populations, however, the tail may be patterned with extended tips. It is considered one of the more tolerant species in the genus.

• At least 60 liters for one male and two females; a separate cave for each female.
• 24–27°C, soft and slightly acidic water; it adapts to moderate hardness.
• Fine sand, dried leaves, roots, plants; a 25% water change every week.

Carnivorous. Frozen bloodworms, brine shrimp, daphnia and cyclops along with small sinking granules are suitable. Live food boosts color and the urge to breed.

It sets up territories on the bottom; males are harsh toward each other. A female guarding fry can become very aggressive; in a small aquarium the male may need to be removed. It gets along well with midwater fish and hunts shrimp.

Good companions: small tetras, pencilfish, hatchetfish, rasboras, otocinclus.

Avoid: shrimp, large cichlids, other Apistogramma males in a small aquarium.
