The Bolivian Ram (Mikrogeophagus altispinosus) is a popular, hardy, and peaceful South American dwarf cichlid. Often called the "Butterfly Ram," it is highly regarded as a more robust and beginner-friendly alternative to its more delicate cousin, the German Blue Ram.
Quick Facts
Scientific Name:Mikrogeophagus altispinosus.
Size: Typically reaches 3 to 3.5 inches (approx. 8–9 cm).
Lifespan: Average of 4 years, though some reach 6 years with optimal care.
Behavior: Peaceful bottom-dweller; exhibits a unique "stop-and-go" swimming style.
Origin: Endemic to the Amazon River basin in Bolivia and Brazil.
Aquarium Care & Environment
Bolivian Rams are "earth eaters" (from the Greek roots geo and phag), meaning they sift through the substrate for food.
Substrate: Fine sand is highly recommended to support their natural sifting behavior.
Tank Size: A minimum of 20 gallons (75L) for a pair, though 30+ gallons is better for a community or small group.
Water Parameters: They prefer a temperature of 75–82°F (24–28°C) and a pH between 6.0 and 7.5.
Decor: Provide plenty of hiding spots with driftwood and plants, plus flat rocks for potential spawning sites.
Diet & Compatibility
Diet: Omnivorous. They readily accept high-quality sinking pellets, flakes, and frozen or live foods like bloodworms and brine shrimp.
Tank Mates: Best kept with peaceful, similarly-sized species such as Tetras, Corydoras, and Guppies. Avoid overly aggressive or much larger fish.
