🌈 Description:

Nanochromis transvestitus is a stunning and unusual dwarf cichlid notable for its sexual role reversal in coloration. Females are more colorful than males, displaying bright red bellies and iridescent highlights, while males are more subdued. This unique trait gives the species its name: “transvestitus” refers to this reversal in traditional coloration roles seen in cichlids. They have a compact, torpedo-shaped body and are best appreciated in a species-specific or carefully selected community setup.

🏠 Tank Requirements:

• Tank Size: Minimum 20 gallons (75 liters) for a pair or small group

• Water Temperature: 75–81°F (24–27°C)

• pH: 6.0–7.0 (slightly acidic preferred)

• Hardness: Soft water (2–8 dGH)

• Filtration: Gentle to moderate flow with good biological filtration

• Aquascape: Caves, leaf litter, driftwood, and rocks; dim lighting; fine sand substrate

• Plants: Optional but helpful for cover (e.g., Anubias, Java fern, floating plants)

🍽️ Diet:

They are omnivores and do best on a varied diet:

• High-quality micro pellets or fine cichlid pellets

• Frozen or live foods (brine shrimp, daphnia, bloodworms, blackworms)

• Occasional vegetable matter or spirulina flakes

Feed in small amounts 1–2 times per day.

🧬 Breeding:

• N. transvestitus is a cave spawner

• Females initiate breeding and care for the eggs and fry

• Males guard the territory

• Provide caves or small flowerpots for spawning sites

• Fry can be fed baby brine shrimp once free-swimming

Breeding may require conditioning with live/frozen foods and slightly acidic, soft water.

🤝 Tank Mates:

Choose peaceful, small species that won’t outcompete them or threaten fry:

• Small tetras (like ember or neon tetras)

• Pencilfish

• Corydoras

• Otocinclus
  Avoid:

• Aggressive or large fish

• Fin-nippers

• Other territorial dwarf cichlids unless the tank is large and well-scaped

📝 Notes:

• Rare and somewhat delicate species, best for intermediate to advanced aquarists

• Sensitive to water quality – weekly water changes (25–40%) are essential

• May be shy without sufficient cover

• Best kept as a pair or alone if tank space is limited
