Astatotilapia nubila - Cichlid Fish for Sale UK

Overview

Astatotilapia nubila, often sold as the Nubile Cichlid, is a hardy and attractive African cichlid that develops real character as it matures. At the 2-3 cm size offered here, these juveniles are still small, but they grow into active, territorial fish with bold behaviour and strong personalities. This species is best suited to aquarists who enjoy keeping cichlids and can provide a properly sized aquarium with stable water conditions and thoughtful stocking.

As a live fish, Astatotilapia nubila is a rewarding choice for keepers looking for something a little different from the more commonly seen Malawi or Tanganyikan species. It is adaptable for an African cichlid, but it still needs the right environment to thrive: good filtration, regular maintenance, and enough space to establish territories. With the correct care, these fish can display attractive colouration and engaging social behaviour.

At Tropical Fish Co, we select healthy stock and pack carefully for fast UK delivery. Every order is covered by our live arrival guarantee, giving you confidence when buying fish online. Please ensure your aquarium is fully cycled and ready before ordering live fish.

Care at a Glance

Origin & Natural Habitat

Astatotilapia nubila is an African cichlid associated with freshwater habitats in East Africa, where it inhabits lakes, lagoons, and sheltered shoreline areas with varied substrate and plant cover. In the wild, fish from this group often live in environments that offer both open swimming space and areas of shelter, allowing them to feed, breed, and establish territories.

Understanding the natural habitat helps when setting up the aquarium. These fish are not delicate, but they do best in clean, mineral-rich water with plenty of oxygen and room to move. Like many cichlids, they appreciate structure in the tank, which helps reduce stress and gives weaker fish places to retreat.

Tank Setup & Water Parameters

Astatotilapia nubila should be kept in a spacious aquarium with strong filtration and regular water changes. A minimum of 200 litres is recommended for a small group or carefully planned community, though larger tanks are always better, especially if keeping more than one male. Use a secure lid, as cichlids can be active and may jump when startled.

Decor should be practical rather than overly delicate. Sand or fine gravel works well, along with rocks, caves, and broken lines of sight to help establish territories. Hardy plants can be used, but choose species that tolerate cichlid activity and possible digging. Many keepers prefer a rock-based aquascape with open swimming areas.

Stable water quality is essential. Keep ammonia and nitrite at zero, and avoid sudden swings in pH or temperature. This species prefers slightly alkaline conditions and moderate warmth. Good aeration is beneficial, especially if the tank is heavily stocked or decorated with rocks.

• Temperature: 23-27°C
• pH: 7.2-8.2
• General hardness: Moderate to hard water
• Filtration: Strong, efficient biological filtration
• Maintenance: Weekly partial water changes recommended

Juveniles of 2-3 cm should be acclimatised carefully and fed small, frequent meals. As they grow, monitor behaviour closely, as dominance and territoriality can increase significantly.

Feeding Guide

Astatotilapia nubila is an omnivorous cichlid with a broad appetite. In the aquarium, it should be offered a varied diet made up of quality cichlid pellets or granules, along with frozen and live foods such as bloodworm, daphnia, mysis, brine shrimp, and chopped earthworm. Vegetable matter is also useful, so include spirulina-based foods and occasional blanched greens where appropriate.

Variety is important for colour, growth, and long-term health. Feed small portions once or twice a day, only as much as the fish will consume in a few minutes. Overfeeding can quickly lead to poor water quality, which cichlids do not tolerate well. Juveniles may benefit from slightly more frequent feeding while they are growing.

Avoid relying on a single food type for long periods. A balanced diet helps support immune function and reduces the risk of digestive issues. If keeping with other cichlids, make sure all fish are getting food, as more assertive tank mates may dominate feeding time.

Tank Mates / Compatibility

This species is best kept with other robust fish that can handle an active cichlid environment. Suitable tank mates include similarly sized African cichlids with comparable water requirements, larger peaceful catfish, and sturdy species that are not easily bullied. In a species tank, behaviour is easier to manage and breeding is more likely.

Because Astatotilapia nubila can become territorial, especially as it matures, avoid slow, timid, or long-finned fish. Small community fish are generally not suitable, and delicate species may be stressed by the cichlid’s activity. If you are keeping a mixed cichlid aquarium, provide plenty of space and visual barriers to reduce aggression.

Sex ratios and stocking density matter. In many cases, keeping one male with multiple females, or maintaining a carefully planned group in a larger aquarium, works better than housing several males in a cramped tank. Always observe behaviour and be ready to separate fish if needed.
