Zebra Obliquidens Cichlid

The Zebra Obliquidens (Astatotilapia latifasciata), also known as the Crimson Tide Cichlid, is a strikingly vibrant freshwater fish native to the Lake Kyoga and Lake Nawampasa systems in Uganda. Though frequently associated with Lake Victoria, it is actually endemic to these neighboring, shallow water lily swamps. Sadly, this species is critically endangered in the wild due to pollution and overfishing, meaning virtually all specimens in the hobby are tank-bred.

They are highly sought after by aquarium hobbyists due to their stunning coloration and relatively peaceful nature compared to other African cichlids.

🐠 Appearance & Sexual Dimorphism

Visuals: Both sexes feature a bright silver-to-yellowish-gold body crossed by 5 distinct, thick vertical black bars.
Males: As they mature, males develop a brilliant, fire-engine crimson red belly and chest, accented by bright yellow highlights.
Females: Females maintain the bold black and silver/gold patterning but completely lack the red coloration.
Size: They grow to a manageable maximum adult length of 4 to 5 inches (10–12 cm).

🏠 Tank Requirements & Water Parameters

Zebra Obliquidens are active swimmers that need plenty of open horizontal space, balanced with visual barriers to manage territorial behaviors.

ParameterRecommended LevelMinimum Tank Size55–75 gallons for a single harem; 125+ gallons for heavy stocking or breeding.Temperature75°F to 82°F (24°C to 28°C)pH Range7.5 to 8.5 (Hard, alkaline water)Substrate & DecorSand or aragonite substrate to buffer pH. Include plenty of rocks, caves, and optional sturdy plants like Tiger Lotus to mimic their natural swamp perimeters.

🍽️ Diet & Feeding

In the wild, they are primarily insectivores. In a home aquarium, they are unpicky omnivores but thrive best on a protein-forward diet to maximize their coloration.

Core diet: High-quality cichlid pellets or flakes.
Protein supplements: Mysis shrimp, brine shrimp, daphnia, and bloodworms (frozen or live).
Digestive health: Occasional spirulina flakes or blanched vegetables to keep their digestive tracts clear.
🤝 Temperament & Tank Mates

They are classified as semi-aggressive. While they can hold their own against pushier fish, they are significantly more peaceful than aggressive Malawi Mbunas.
- Best arrangement: Keep them in a harem setup (1 male to 2–3+ females) to spread out the male's breeding energy.
- Good tank mates: Similarly sized, mildly tempered African cichlids like Peacocks (Aulonocara), Yellow Labs, or other Lake Victorian cichlids.
- Avoid: Highly aggressive Mbuna species or overly fragile, slow-moving community fish.
