Apistogramma sp. Breitbinden A165

A Little More Information...

Apistogramma sp. Breitbinden A165 is a South American dwarf cichlid still kept under a trade designation rather than an officially described species name. Listed under the aquarium code A165, it is known for its broad vertical bands, which inspired the German name Breitbinden. This form remains uncommon in the aquarium trade, and available specimens are wild-collected. Like many Apistogramma, it requires soft, warm, acidic water, a highly structured layout with shelters, and a varied diet. Its territorial behavior becomes especially interesting during breeding, when the female usually occupies and defends a small cavity.

General species description

Apistogramma sp. Breitbinden A165 refers to an undescribed form of the genus Apistogramma, recognized in the aquarium hobby by the code A165. It is a territorial dwarf cichlid, generally peaceful toward open-water fish but more assertive around its shelter or brood. Its availability is limited: it is uncommon and is mainly offered through specialized shipments. This fish is best suited to aquarists able to maintain very soft, acidic water with stable parameters and to provide several separate hiding places.

Geographical origin and biotope

Reference country: Peru. The form is associated with the Rio Nanay basin in northeastern Peru. Its natural environment consists of calm sections of small forest streams, often darkened by tannins. The bottom is typically made up of leaf litter, fine sand, and woody debris. Dense riparian vegetation creates subdued light and many sheltered areas. In an aquarium, these conditions can be approximated with roots, dried leaves, and plants that tolerate soft water.

Precise location and local name

In the aquarium trade, Apistogramma sp. Breitbinden A165 is mainly identified by its A165 code and by the German name Breitbinden, meaning “broad-banded.” This designation helps identify the form while it remains outside a definitive scientific classification. A regional vernacular name is not commonly used for this form. To preserve its identity, it is preferable to retain the A165 code and avoid mixing fish from different populations.

Appearance and physical characteristics

The body is elongated, laterally compressed, and typical of small Apistogramma. Its pattern consists of broad, contrasting vertical bands over a beige-brown to grayish background, with changes according to mood, sex, and social context. The fins may show yellow, orange, or blue tones. The adult male reaches approximately 6 cm, while the female remains smaller. During breeding, the female may become more intensely yellow and actively defend a cavity.

General diet

Apistogramma sp. Breitbinden A165 is a micro-predator that searches through leaf litter and submerged surfaces for small prey. Its diet should emphasize small, nutritious foods such as brine shrimp, daphnia, cyclops, and bloodworms, either fresh or frozen. Fine-quality pellets may be offered as a supplement but should not be the sole food. Small portions given regularly help maintain condition. Wild specimens may need a gradual transition to prepared foods; clean water and dietary variety are important for long-term health.

In your aquarium

Success with Apistogramma sp. Breitbinden A165 depends on soft, acidic, stable water and a highly structured aquarium. Provide several shelters, roots, and leaf litter to reduce territorial pressure. Because these fish are wild-collected, patient acclimation and frozen or live foods are especially helpful. A pair or small group may work depending on aquarium size, but each female should have access to a separate refuge. Avoid boisterous tankmates and monitor water parameters after every water change. Maintaining the A165 code also helps preserve the identity of this uncommon aquarium form.
