CW217 Rio Tomo Concolor Cory (Hoplisoma concolor) – The Stunning Two-Toned Bottom Dweller

Looking for a truly special addition to your cleanup crew? The CW217 Rio Tomo Concolor Cory, recently reclassified as Hoplisoma concolor (formerly Corydoras concolor), is a rare and highly sought-after variant collected from the Rio Tomo region in Colombia. What makes this specific location variant so desirable is its breathtaking two-toned coloration. The front half of their body boasts a metallic, slate-grey to blueish hue, which beautifully transitions into a striking rust, orange, or reddish coloration on the rear half and fins. Like all Cory cats, they are peaceful, highly social, and endlessly entertaining to watch as they scurry along the bottom of the aquarium searching for food. This rare gem is a must-have for both dedicated Corydoras collectors and planted tank enthusiasts alike.

Key Features 

• Exceptional Coloration: Features a unique slate-grey/blue body that sharply contrasts with vibrant orange-red dorsal and caudal fins.

• Rare CW217 Variant: A specific collection point (Rio Tomo) known for producing some of the most vibrantly colored Concolor Corys in the hobby.

• Peaceful Schooling Nature: Extremely docile and thrives in groups, making them the perfect bottom-dweller for community aquariums.

• Active Cleaning Crew: Constantly sifts through the substrate for uneaten food, helping to keep your tank clean.

• Hardy & Adaptable: An excellent choice for intermediate aquarists looking to keep wild-type or rare species.

Care Requirements

• Tank Size: Minimum 20 gallons. They must be kept in schools of at least 6 individuals (more is always better) to feel secure and exhibit natural behaviors.

• Water Temperature: 72–79°F (22–26°C)

• pH Range: 6.0–7.2 (Prefers slightly acidic to neutral water).

• Diet: Omnivorous – feed a high-quality sinking diet. Sinking pellets, algae wafers, and regular offerings of frozen or live foods (bloodworms, blackworms, brine shrimp) are essential for their health and coloration.

• Tank Mates: Ideal companions include peaceful, small to medium-sized fish such as Tetras, Rasboras, peaceful Dwarf Cichlids (like Apistogramma), and other non-aggressive community fish.

• Habitat Setup: A soft sand substrate is absolutely mandatory. Sharp gravel or rough substrates will damage their delicate sensory barbels, leading to stress and infection. Provide plenty of hiding spots using driftwood, smooth river stones, and dense plants.
