Remarks: Wallaciia regani (formerly known as Crenicichla regani) is a species of dwarf pike cichlid native to the Amazon River basin in South America. It is one of the most common and widespread members of the Wallaciia genus, which was officially erected in 2023 to house the dwarf species formerly classified within the Crenicichla wallacii species complex.
Physical Characteristics: This is one of the smallest pike cichlids, typically reaching a maximum length of about 7.9 cm (3.1 in).
They have an elongated, "pike-like" body shape. Females often exhibit distinctive black ocelli (eye-spots) rimmed with white on their dorsal fin, which helps distinguish them from similar species like W. notophthalmus.
Because they are found throughout Central Amazonia, their appearance can vary significantly by location, leading some researchers to believe W. regani may actually be a complex of several very similar species.
Distribution: Found primarily in the Amazon River basin and the Trombetas River in Brazil.
They prefer the calmer waters of small tributaries, often in areas thick with leaf litter and submerged roots.
In the wild, they typically inhabit soft, acidic water with a pH range around 6.0 to 7.2 and temperatures between 24°C and 27°C (75°F–81°F).
Classified as Least Concern by the IUCN Red List.
Aquarium Care
Tank Size: A minimum of 30 gallons is generally recommended.
Temperament: While "peaceful" compared to larger pike cichlids, they are still territorial and predatory. They may eat smaller tankmates like shrimp or nano-fish but generally ignore larger, non-aggressive fish.
Setup: Provide plenty of hiding places using driftwood, rocks, and caves to help them establish territories.
Diet: As micropredators, they thrive on live or frozen foods such as bloodworms and krill, though some can be transitioned to high-quality dry foods.

Ordering FAQs
Will my fish look like the picture?
The majority of fish on our website will NOT look like their photos upon their unboxing. Fish change in appearance depending on many factors, including mood, age, gender, and social status. Fish will naturally lose color during shipping and may appear faded upon arrival. Pictures are used as examples only. Pictures may be of mature fish with full color or juvenile fish without color. We encourage you to research the species as much as possible prior to ordering in order to familiarize yourself with the various appearances they may take on. Many species have females that look drastically different to their male counterparts, and many juveniles will not have as much color (or different colors) as their adult forms. If you have questions about how the fish will look, please review their information and email us if you have any questions.
How do I know which fish can go together in my tank?
Research the product descriptions on our website and use Google search to help decide which fish can go together. PLEASE do your research and email us if you have any questions. Also, we have a very active Facebook group called Imperial Tropicals Fishkeepers where you can learn from knowledgable and experienced fishkeepers.
