Kribensis — ‘kribs’ — are arguably the best cichlid for a beginner. They’re small, hardy, wonderfully colourful (especially the females’ cherry-red bellies), and peaceful enough for a community tank outside of breeding. They also breed readily and make devoted parents, offering a first taste of cichlid behaviour without the aggression of bigger species. This UK guide covers kribensis care.

Here’s how to keep them.

Quick facts

• Adult size: 8–10 cm
• Tank size: 90 litres for a pair
• Water: pH 6.0–7.5, adaptable, 24–28 °C
• Lifespan: 5 years
• Temperament: peaceful, territorial when breeding

Tank setup with caves

Kribs are cave-spawners, so provide caves — a coconut shell or clay pot on its side is perfect. Give a pair 90 litres-plus with planting and a soft substrate. They’re adaptable to most UK water. Feed a varied diet of quality cichlid granules and frozen foods.

Breeding and temperament

Kribs pair off and breed easily in caves, and become temporarily territorial while guarding fry — a fascinating behaviour to watch. Outside breeding they’re peaceful community fish. Give tank mates space to stay clear of the nest cave during spawning.

Tank mates

Good with peaceful mid-and-upper level fish that stay out of their cave zone: tetras, rasboras, gouramis and robust bottom fish. Avoid other cave-spawning cichlids that compete for territory.

Frequently asked questions

Are kribensis good for beginners?

Yes — they're among the best beginner cichlids: small, hardy, colourful and peaceful outside of breeding, offering a first taste of cichlid behaviour without the aggression of larger species.

What size tank do kribensis need?

At least 90 litres for a pair, with caves and planting. More space helps tank mates stay clear of the nest cave when the kribs are breeding.

Do kribensis need caves?

Yes — they are cave-spawners, so a coconut shell, clay pot or similar cave is important both for security and for breeding. Without one they may feel exposed and stressed.
