Appearance and Sexual Differences
- Short Description: A large, robust cichlid with a powerful build, thick lips, and a strong jaw. It is most often sold in its solid bright red or orange color morph. Males often develop a subtle nuchal hump (forehead growth) as they mature.
- Coloration: Varies, but the most popular form is a solid, vivid red or orange. Males are generally larger, have a more convex head profile (nuchal hump), and have more pointed dorsal and anal fins. Females are slightly smaller and fuller-bodied.
- Fins: Strong, thick fins that are well-adapted for fighting and asserting dominance.
- Behavior: Fiercely territorial and aggressive. They are active diggers and will rearrange the substrate and decor to their liking. They are highly interactive with keepers but will attack and kill most tank mates.
Tank Requirements and Water Parameters
- Minimum Tank Size: 75 gallons (280 liters) is the minimum for a single adult. A 125-gallon tank or larger is required for a compatible adult pair.
- Schooling: Best kept as a solitary centerpiece fish (species-only tank). If a bonded pair is kept, the tank must be very large (125+ gallons) with ample visual barriers. Never keep two non-mated males together.
- Temperature: Tropical range: –– (up to is tolerated).
- pH Level: Neutral to slightly alkaline: 6.5 to 8.0 (or higher, depending on origin). They require powerful filtration and large, frequent water changes (25–30% weekly) to manage the massive amount of waste they produce. Water flow should be moderate.
- Aquascape: Requires a fine sand substrate (they love to dig). Use large, smooth rocks and securely anchored driftwood to create caves and barriers; unsecured decor will be moved or toppled. Avoid live plants as they will likely be uprooted or eaten. All equipment (heaters, filters) must be protected or hidden outside the tank.
Diet and Feeding
The Red Devil Cichlid is a large, opportunistic omnivore that requires a varied diet.
- Staple Diet: High-quality large cichlid pellets or sticks formulated for Central/South American omnivorous cichlids.
- Supplementation: A varied diet is essential. Offer protein-rich frozen or live foods regularly: Earthworms, Crickets, Chopped Prawns/Krill, and Bloodworms. Also require vegetable matter: blanched peas, lettuce, or spirulina flakes.
- Schedule: Feed 2–3 times daily in small portions that are consumed quickly. Overfeeding can lead to health issues like obesity and Hole-in-the-Head disease (HITH).
Compatibility
- Caution: Extremely aggressive and territorial. Best kept in a species-only tank. If tank mates are attempted, they must be equally large, robust, and fast-moving, and occupy different water columns. Will kill and eat smaller fish.
- Good Tank Mates (in very large tanks): Large, tough cichlids (e.g., Oscars, Flowerhorn, Jack Dempsey), large armored catfish (Plecos, Synodontis), and some large Barbs (Tinfoil). Tank mates are always a risk with this species.
