Apistogramma hongsloi: A Comprehensive Guide

Apistogramma hongsloi, also known as Hongslo's Dwarf Cichlid, is a popular species among aquarists due to its striking coloration and interesting behavior. This guide covers everything you need to know about Apistogramma hongsloi, from their natural distribution and habitat to their dietary needs and spawning practices, including the various color morphs available.

Distribution and Habitat

Apistogramma hongsloi is native to the Orinoco River basin in Colombia and Venezuela. They inhabit slow-moving or still waters with dense vegetation and submerged leaf litter, which provide ample hiding spots and breeding grounds. These environments are typically characterized by soft, acidic water and sandy or muddy substrates.

Size and Appearance

Apistogramma hongsloi grows to a size of about 3 inches (7.5 cm). They have an elongated body with a slightly rounded head and a distinctive dorsal fin. This species is known for its vibrant colors, which can vary significantly between individuals and color morphs. Apistogramma hongsloi II is a commercial name for very red color morphs produced from selective breeding.

Water Parameters

Maintaining optimal water conditions is crucial for the health of Apistogramma hongsloi:

  • Temperature: 75-82°F (24-28°C)
  • pH: 5.5-7.0
  • Hardness: 0-8 dGH

These fish thrive in well-maintained aquariums with soft, acidic water and moderate filtration to mimic their natural habitat.

Tank Mates

Apistogramma hongsloi are generally peaceful but can be territorial during breeding. Suitable tank mates include:

  • Rainbowfish
  • Rasboras
  • Corydoras
  • Pencil Fish
  • Other peaceful dwarf cichlids

Avoid housing them with larger or more aggressive fish that might intimidate or harm them.


In the wild, Apistogramma hongsloi are omnivores, feeding on small invertebrates, plant matter, and detritus. In captivity, they thrive on a varied diet:

  • High-quality pellets or flakes formulated for cichlids
  • Live or frozen foods such as bloodworms, brine shrimp, and daphnia
  • Repashy Community or Spawn and Grow

A varied diet ensures their vibrant coloration and overall health.


Apistogramma hongsloi are active and engaging fish, often seen exploring their environment and interacting with tank mates. They are best kept in pairs or harems (one male with multiple females) to promote natural behaviors and reduce aggression.


Breeding Apistogramma hongsloi in captivity is relatively straightforward, making them a favorite among aquarists. Key points include:

  1. Conditioning: Feed the breeding pair or group a high-protein diet, including live and frozen foods, for several weeks.
  2. Breeding Tank: Set up a separate breeding tank with plenty of hiding spots, such as caves, driftwood, and dense plants. Maintain optimal water conditions with good filtration.
  3. Spawning Process: Males will display vibrant colors and court females, who lay adhesive eggs on surfaces such as plant leaves, rocks, or inside caves. The female guards the eggs and fry while the male defends the territory.
  4. Hatching: Eggs typically hatch within 2-3 days. Feed the fry infusoria or liquid fry food until they are large enough to consume baby brine shrimp.
