(500) Motoro Hybrid Stingrays 8in

Motoro Hybrid Stingrays are a captive-bred freshwater fish known for their striking patterns, which are often enhanced compared to wild Motoro rays (Potamotrygon motoro). They are a fascinating, though demanding, species that require significant space and pristine water conditions. Due to their large size and high waste output, they are only suitable for experienced aquarists. 

• Tank size: For a single adult male, a minimum of a 220- to 300-gallon aquarium is required. Females can grow larger, requiring 300 to 400 gallons or more. For groups, a 500-gallon-plus system is necessary. The tank's footprint is more important than height; a surface area of at least 8x3 feet is ideal for adults.
• Substrate: A very fine, soft sand substrate is crucial to prevent abrasions to the ray's delicate underside. Never use gravel or large pebbles, as they can cause injury and trap waste. A bare-bottom tank is also an option and can make cleaning easier.
• Filtration: An oversized, powerful filtration system is essential to handle their heavy bioload and maintain the pristine water quality they require. A sump system is highly recommended.
• Decor: The tank should provide ample open swimming space. Use minimal decor, consisting only of smooth driftwood or rounded, non-sharp stones.
• Lighting: Subdued lighting is best, as they prefer lower light levels.
• Lid: A tightly-fitting, weighted lid is mandatory. Stingrays are known to be able to climb and jump out of aquariums, especially during feeding. 

• Maintenance: Large, weekly water changes of 30–50% are essential due to their high waste output. 

• Primary foods: A combination of high-quality sinking carnivore pellets, shrimp, earthworms, bloodworms, and frozen fish like silversides.
• Feeding schedule: Feed 1–2 times daily. Young rays will require more frequent, smaller feedings. Promptly remove any uneaten food to prevent water contamination. 

• Temperament: They are generally peaceful but predatory. Keep them with other large, peaceful, mid-water fish that will not be eaten or harass the ray.
• Tank Mates:
  • Good companions: Large, non-aggressive fish like Arowana, Datnoids, Peacock Bass, and larger Severums.
  • Avoid: Aggressive cichlids like Oscars, small fish that can be eaten, and anything that might compete for food. Avoid Loricariids (suckermouth catfish) which can injure them.
• Defense: Handle with extreme caution. The venomous barb on their tail is used for defense and can inflict painful wounds. Seek medical help if you are stung.
• Lifespan: With proper care, they can live for 15–20 years
