Will it fit your tank?
Compare it with your tank's species, size, water tests and country.
Water
- Comfortable
- Acceptable, less ideal
- Tolerated, not comfortable
Space
Needs 8–15, depending on how it is kept
Needs 400–880 L, depending on how it is kept
- The space it needs, from the least to the most generous
- Recommended
Character and care
- TemperamentUsually peaceful; can be semi-aggressive towards its own kind
- Social lifeIn groups
- DietHerbivore
Legal rules
The least the law allows, by country: the water and space above are what the species needs. A tank is checked against its own country's rules.

4 notes from the rules
Grazes on algal growth
Cichlids are aggressive, especially during brood care. Provide a well-structured tank with hiding places for subordinate fish and for the partner.
What matters for hardness is a sufficiently high carbonate hardness, and pH must not fall below 7.0.
Austria, general duties for freshwater fish: aim for middle values of the temperature, hardness and pH ranges; adjust new fish slowly to the water; change part of the water regularly, with water of the same quality; check temperature daily, and pH, hardness and nitrate at least every 14 days; check nitrite daily during the first six weeks of a new tank; give a clear day–night cycle; provide free swimming space, filter, heater and pump, substrate, hiding places and plants where the fish allow; keep the species according to its social structure; species kept together must suit each other in water quality, temperature and social behaviour (§ 7 (5); Anlage 5, 1.1).
Switzerland
4 rules
- At least 12 L of water per animal
- Tank length at least 36 cm
- Tank width at least 24 cm
- Tank height at least 12 cm
Note from the rules
Switzerland, general duties for ornamental fish: minimum volume = each fish's current body length (snout to tail base) × litres per cm by size class (up to 5 cm 0.5; 10 cm 0.75; 15 cm 1; 20 cm 1.25; 30 cm 1.75; 40 cm 2.25; over 40 cm 3), summed over all fish, plus species-specific needs; the tank at least 3 times as long and 2 times as wide as the largest fish's body length, and the water at least that deep; not visible from all sides, with visual cover and retreats; a day–night rhythm; water quality suited to the species; no prolonged strong vibration; social species need contact with their own kind; prevent excessive breeding; genetically modified fish such as GloFish are banned (TSchV Art. 13, 25, 98 and Anhang 2 Tabelle 8).
