Overview
The sunset dwarf cichlid is a small, mostly peaceful apisto for the bottom of a soft, acidic blackwater tank. It is a good step up from beginner fish.
Did you know
A brooding female sunset dwarf cichlid does sentry duty from inside a leaf-litter cave. She will headbutt fingers, siphons and fish many times her size.
Caring for the sunset dwarf cichlid
House a pair of sunset dwarf cichlids in at least 16 gal (60 L), with at least two caves. Each female claims a tight territory around her spawning site. Use sand with a deep leaf layer and tangles of wood.
Keep the water soft and acidic, at 75 to 82°F (24 to 28°C) and a pH of 4.8 to 6.5. Dim, tannin-stained water brings out the orange body color behind its common name. It eats small live and frozen foods readily and learns to take sinking prepared food.
The sunset dwarf cichlid is mostly peaceful and keeps to the bottom. Calm midwater dithers such as pencilfish help the pair feel safe enough to stay out.
Males have a smoky orange body and a bold dark shoulder blotch. Females turn brilliant yellow with a black chest band when they guard the brood from a cave. Soft water is a must for breeding, since eggs fail in hard water. They are moderately hard to breed.
Good to know
The sunset dwarf cichlid, Apistogramma atahualpa, is a member of the cichlid family, Cichlidae, described by Uwe Römer in 1997. It is named for Atahualpa, the last Inca emperor. The hobby traded it as the sunset apisto before it was described.
In the wild
The sunset dwarf cichlid lives in the Rio Nanay system near Iquitos, Peru. The Nanay is a blackwater river over white sand, and the fish shelters in banks of sunken leaves.
