Jurua Dwarf Cichlid (Apistogramma juruensis) – Specialist Cave-Spawning Apistogramma

Jurua Dwarf Cichlid (Apistogramma juruensis) is a small Brazilian cave-spawning cichlid from the upper Juruá River basin. It is a specialist bottom-oriented fish for mature aquariums with soft substrate, several shelters and calm, stable water.

There is an important evidence issue around adult size. FishBase lists a 2.4 cm standard-length record from scientific material, while specialist aquarium references report living adults substantially larger, often around 7–9 cm for males. Those figures are not directly interchangeable, and the preserved FishBase record should not be presented as a guaranteed adult aquarium maximum. This page therefore avoids pretending one exact figure is settled.

What aquarium setup does it need?

Use fine sand with leaf litter, wood, shaded zones and several small caves. Each female in a multi-female setup needs her own defensible shelter. The aquarium should provide broken sight lines so one fish cannot control the entire bottom.

Gentle filtration is suitable as long as the biological filter is mature and oxygenation remains adequate. Keep ammonia and nitrite at zero and avoid abrupt chemistry changes. Dimmer lighting or floating cover often produces more confident behaviour.

How should it be stocked?

A compatible pair is the simplest plan in a modest aquarium. A harem-style group can work in a larger footprint with multiple caves and clear territories. Current Shopify stock does not specify sex, so do not assume two randomly selected fish form a male/female pair.

What should I feed it?

Use appropriately sized frozen and live foods such as Artemia, daphnia, cyclops and bloodworm in rotation, supported by a good sinking micro pellet once the fish accepts prepared food. Feed small observed portions and make sure midwater fish do not take every item before it reaches the territory.

Frequently asked questions

How large does Apistogramma juruensis get?

Published sources conflict. FishBase records 2.4 cm standard length from scientific material, while specialist aquarium references report much larger adult total lengths. Plan the tank conservatively for a normal small Apistogramma rather than using the 2.4 cm record as a housing limit.

Is it suitable for a 30-litre tank?

No. Use roughly 60–80 litres or more for a properly structured pair setup, and more for multiple females or community fish.

Does it need caves?

Yes. It is a cave-spawning Apistogramma, and female territory is centred on secure shelters.

Can it live with tetras?

Small peaceful midwater fish can work in a sufficiently large aquarium when water chemistry overlaps. Avoid species that crowd the bottom or outcompete the cichlids at feeding time.

Can it live with shrimp?

Do not rely on it as shrimp safe. Small shrimp and shrimplets can be eaten by a bottom-oriented micropredatory cichlid.

Is the fish sold as a pair?

No pair or sex guarantee is included unless a future live variant explicitly states it.

Evidence note: accepted identity, distribution, temperature records and cave-spawning behaviour were checked against FishBase and specialist cichlid references. Conflicting size information is stated openly rather than converted into a false single-number certainty.
