The Red Devil Cichlid is one of the most impressive yet challenging representatives of American cichlids. While I wouldn’t recommend this fish for typical home aquariums, it becomes a true centerpiece in spacious office environments and public spaces. Its imposing size, distinctive appearance, and charismatic behavior never fail to captivate visitors.
Classification and Synonyms
| Parameter | Value |
|---|---|
| Kingdom | Animalia |
| Phylum | Chordata |
| Class | Actinopterygii |
| Order | Perciformes |
| Family | Cichlidae |
| Genus | Amphilophus |
| Species | Amphilophus labiatus |
Synonyms: Cichlasoma labiatum, Herichthys labiatus, Cichlasoma dorsatum, Heros labiatus
Common names: Red Devil Cichlid, Large Lipped Cichlid
Natural habitat: Endemic to Lakes Managua and Nicaragua in Central America. Inhabits deep volcanic lakes with rocky bottoms.
Description and Appearance
The defining characteristic of this species is its massive, fleshy lips that form a distinctive double ridge in profile—hence the scientific name labiatus. This feature has earned the fish its alternative common name, the Large Lipped Cichlid.
In nature, the Red Devil Cichlid reaches 30-35 cm in length. Under aquarium conditions, specimens typically grow to 15-20 cm, though with spacious accommodations they can approach their natural size. In my experience, males in optimal conditions easily reach 25 cm.
Coloration varies from dull yellow and gray to brilliant orange and red. Color intensity depends on maintenance conditions, diet, and the fish’s emotional state. Some individuals display black spots or stripes on their bodies.
Distinguishing from Midas Cichlid
The Red Devil Cichlid is frequently confused with the Midas Cichlid (Amphilophus citrinellus), especially in juvenile stages. This leads to uncontrolled hybridization, prompting some specialists to claim that finding purebred Amphilophus labiatus in aquariums is nearly impossible.
Key differences:
- Head shape: Red Devil has a more elongated snout, resembling a fox’s muzzle
- Lips: Red Devil’s lips are significantly larger and fleshier
- Coloration: less reliable due to high variability in both species
Avoid keeping these species together to prevent interspecies hybridization.
Sexual Dimorphism
Females are approximately 1.5-2 times smaller than males. Males possess longer, more pointed dorsal and anal fin tips. Adult males develop a pronounced fatty nuchal hump on the forehead, which becomes especially prominent in dominant individuals and during breeding periods.
Important note: females mature later than males—a factor you must consider when forming pairs. Mismatched sexual maturity can trigger aggression from a breeding-ready male toward an immature female.
Behavior and Temperament
The Red Devil Cichlid is an intensely territorial predator with high aggression levels. In my experience, this ranks among the most problematic cichlids for community compatibility. Aggression escalates dramatically during spawning, when fish may even attack their owner’s hand.
Interesting trait: when kept solitarily, these fish often show friendliness toward humans, recognize their owner, and may take food from hand. They demonstrate considerable intelligence and curiosity.
Sexual maturity is reached at 9-15 months. Lifespan under good conditions spans 10-12 years, though individual specimens with ideal care may live longer.
Tank Requirements and Water Parameters
Aquarium Size
Keeping a Red Devil Cichlid is a task for experienced aquarists with space for substantial tanks. Minimum volume for a single specimen is 250-300 liters. A pair requires 400-500 liters minimum. If planning cohabitation with other large cichlids, volume should start at 800-1000 liters.
I recommend external filtration with 4-6 tank volumes per hour turnover—these fish create significant biological load. Powerful aeration is mandatory.
Water Parameters
| Parameter | Value |
|---|---|
| Temperature | 24-26°C (acceptable 22-28°C) |
| pH | 6.5-8.0 (optimal 7.0-7.5) |
| Hardness (dGH) | 6-25° (optimal 10-20°) |
| Water changes | 25-30% weekly |
| Ammonia/Nitrites | 0 ppm |
| Nitrates | < 20-30 ppm |
These fish are fairly hardy and adapt to a wide parameter range, but stability is critical for health. Poor water quality leads to hole-in-the-head disease and other conditions.
Tank Decoration
Substrate: Dark gravel of medium to large grain (5-15 mm). Dark substrate promotes more saturated coloration and reduces stress levels. I recommend granite chips or river pebbles.
Decorations: Large rocks positioned vertically every 40-50 cm serve as visual territory boundaries. Create caves, grottoes, and canyons from large stones—these provide refuge for weaker individuals. Driftwood is welcome and adds natural aesthetics.
Critical: all decorations must be stable and heavy—fish constantly rearrange the landscape to their liking.
Lighting: Moderate, not critical for the fish themselves. Select based on plant needs and aesthetic preferences.
Plants
Red Devil Cichlids actively dig substrate and frequently uproot plants. Nevertheless, dense vegetation helps create hiding spots and reduce aggression. I recommend:
- Tough-leaved species with robust root systems (Anubias, Cryptocoryne)
- Potted plants secured with rocks
- Fast-growing species you won’t mind losing
- Floating plants to diffuse light
In my experience, accept periodic plant damage—complete protection is impossible, but their presence positively influences fish behavior.
Compatibility with Other Fish
The Red Devil Cichlid ranks among the most difficult species for selecting tankmates. Small fish are perceived exclusively as food. Slow-moving and peaceful species will face constant harassment.
Possible tankmates:
- Other large American cichlids of similar size and temperament (Diamond Cichlid, Oscars, Managua Cichlids)
- Large armored catfish
- Pterygoplichthys species
Mandatory conditions when keeping with neighbors:
- Raising together from juvenile stage
- Spacious aquarium (800-1000+ liters)
- Clear territorial division
- Multiple hiding spots
- Constant monitoring of interactions
Absolutely incompatible with:
- Small species (tetras, barbs, gouramis)
- Slow-moving fish
- Midas Cichlid (hybridization risk)
I strongly recommend species-only keeping—solitary or as a pair. This eliminates numerous problems and stresses for both fish and owner.
Feeding
The Red Devil Cichlid is an omnivorous predator with excellent appetite. In nature, it feeds on small fish, crustaceans, mollusks, insects and their larvae, plus plant matter.
Aquarium Diet
Protein foods (70% of diet):
- Quality pellets and granules for large cichlids
- Frozen foods: bloodworms, brine shrimp, shrimp, mussels
- Earthworms (pre-chopped)
- Pieces of lean fish (occasionally)
Plant supplements (30% of diet):
- Spirulina
- Blanched vegetables: zucchini, cucumber, spinach, peas
- Paprika (bell pepper)—for maintaining vibrant coloration
- Lettuce leaves
Important to avoid:
- Warm-blooded animal meat (beef, chicken, liver)—poorly digested and pollutes water
- Live fish as staple food (disease risk)
- Cheap feeds of questionable quality
Feeding Schedule
I feed adult fish 1-2 times daily with portions consumed within 2-3 minutes. Juveniles receive 2-3 feedings daily. One fasting day weekly benefits digestion.
For maintaining bright orange-red coloration, I recommend specialized carotenoid-enhanced foods (Tetra Cichlid Colour, Sera Cichlid Red XL, JBL Grana Color). In my experience, combining such feeds with paprika and brine shrimp yields excellent results.
Breeding
Pair Formation
Breeding Red Devil Cichlids involves specific challenges and risks. The primary problem is aggression from incompatible partners or differences in sexual maturity.
Safe pairing methods:
- Raising a juvenile group together—fish select their own partners
- Gradual introduction through divider—breeders kept in one tank separated by transparent partition until signs of mutual interest appear
- Size and readiness matching—female must be large and mature
Never directly introduce unfamiliar adults—this almost guarantees fighting.
Spawning Stimulation
After pair formation, I stimulate spawning through:
- 25-30% water change with fresh water
- Temperature increase by 2-3°C (to 27-28°C)
- Enhanced protein feeding
- Placing flat stones in secluded areas
Breeding Process
The pair selects a secluded location and meticulously cleans a flat stone or other surface. The female deposits several hundred to 1000-1500 eggs (quantity depends on size and maturity). Eggs are yellow-orange colored.
Incubation lasts 3-5 days depending on temperature. Parents then transfer larvae to a pre-dug pit. After 4-7 days, fry begin swimming horizontally and feeding.
In nature, Red Devil Cichlids feed fry with special skin secretions. In aquariums, starter foods for juveniles include:
- Brine shrimp nauplii
- Microworms
- Specialized cichlid fry foods
- Crushed boiled egg yolk (cautiously)
Parents are attentive and aggressive guardians of offspring. Fry up to 2-3 weeks old may hide in parents’ mouths when threatened. During this period, avoid disturbing the family and especially inserting hands in water—adult bites are painful and can cause injury.
Raising Juveniles
Fry grow rapidly with abundant feeding. By 2 months they reach 3-4 cm. Sexual maturity arrives at 9-15 months.
Important consideration: before triggering spawning, consider the offspring’s future. Due to large size and aggression, demand for these fish is limited. Even pet stores reluctantly accept juveniles. I recommend breeding Red Devils only with pre-arranged buyers.
Diseases and Prevention
Under good conditions, the Red Devil Cichlid is fairly robust. Primary issues relate to:
- Hexamita (hole-in-the-head disease)—result of poor water quality and unbalanced nutrition
- Bacterial infections—from injuries after fights
- Parasites—when feeding live foods of questionable quality
Prevention:
- Stable water parameters
- Regular water changes
- Quality varied nutrition
- Quarantine for new fish
- Stress minimization
Who Should Keep This Fish?
The Red Devil Cichlid is not a fish for typical home aquariums. Its maintenance requires:
- Spacious premises for installing 300+ liter tanks
- Financial capacity (equipment, food, electricity)
- Experience with large aggressive cichlids
- Acceptance of limited species diversity
Ideal placement options:
- Office aquariums
- Building lobbies and organizations
- Public spaces
- Spacious private homes with dedicated rooms
Impressive size, distinctive appearance with characteristic lips, and vibrant coloration make this fish an excellent element of representative design. In my experience, visitors invariably notice these charismatic giants.
For home keeping, I would recommend beginners consider more compact and peaceful species—for example, Blood Parrot, which despite similar color vibrancy are significantly smaller and calmer.
Conclusion
The Red Devil Cichlid is an impressive fish for those prepared to provide appropriate conditions. Its aggression and size present serious challenges, but charisma, intelligence, and decorative appeal amply compensate for maintenance difficulties. With proper approach, these fish become true long-lived centerpieces of any spacious aquarium.
