OHM Aurora purple

OHM Aurora purple — a stunning, aggressive bettas species requiring high pH water; perfect for experienced aquarists seeking vibrant colour and bold personality.

• Water Conditions: The OHM Aurora purple demands stable, high-pH aquatic environments to truly thrive. Aim for a pH range between 7.8 and 8.6, with water hardness (GH) maintained between 12 and 20 dGH. Temperature should be kept consistently between 24°C and 28°C (75°F–82°F). These fish originate from alkaline rift lake environments, meaning soft, acidic water will cause significant stress, suppressed immunity, and reduced colouration. Regular water changes of 25–30% weekly are essential to maintain excellent water quality, as this species produces a considerable bioload. Invest in a high-quality filtration system capable of handling robust waste output, and consider adding crushed coral or limestone substrates to naturally buffer the water and maintain those elevated pH levels. Never introduce this fish into an uncycled or unstable aquarium, as sudden parameter swings can prove fatal.
• Aquarium Setup: Given the aggressive nature of the OHM Aurora purple, tank size is non-negotiable. A minimum of 200 litres (approximately 55 gallons) is required for a single specimen, with larger volumes — 300 litres or more — recommended if you intend to keep a small group or a mixed community of similarly robust species. Provide plenty of rockwork, caves, and crevices to create distinct territories and hiding spots, which helps diffuse aggression and allows subordinate fish to retreat when necessary. Use smooth-edged rocks to prevent injury, and arrange them in stable structures that won't collapse. A sandy or fine-gravel substrate is ideal, as these fish are natural diggers and will rearrange their environment to suit their preferences. Open swimming areas should also be maintained to allow for natural cruising behaviour. Lighting should be moderate, mimicking the bright, clear conditions of their native habitat.
• Tank Mates: The aggressive temperament of the OHM Aurora purple makes tank mate selection a critical consideration. Suitable companions include other robust, large cichlid species that share similar water parameter requirements — such as other Rift Lake cichlids, which are equally tough and accustomed to high-pH conditions. Avoid small, peaceful, or slow-moving fish, as they will be perceived as prey or targets for bullying. Do not house them with invertebrates like shrimp or snails, as these will be quickly consumed. When keeping multiple Aurora purples together, overstocking slightly (within reason) can actually help disperse aggression, a technique commonly used by cichlid keepers. Always introduce all tank mates simultaneously or rearrange the aquascape when adding new fish — this disrupts established territories and reduces the likelihood of fatal confrontations. Monitor interactions closely during the first few weeks to ensure compatibility.
• Feeding Habits: In the wild, the OHM Aurora purple is primarily carnivorous and piscivorous, though it will also opportunistically consume invertebrates. In captivity, provide a varied, protein-rich diet to maintain optimal health, growth, and colour intensity. High-quality cichlid pellets or sticks formulated for carnivorous species should form the dietary staple. Supplement this with live or frozen foods such as brine shrimp, bloodworms, krill, mysis shrimp, and chopped fish fillet. Some vegetable matter, such as spirulina flakes, can also be offered to provide dietary balance. Feed adults once or twice daily, offering only what they can consume within two to three minutes to prevent overfeeding and water pollution. Juveniles should be fed smaller portions more frequently — up to three times daily — to support rapid growth. Avoid feeding mammalian meat such as beef heart, as this can cause digestive issues and fatty liver disease in cichlids.
• Care Requirements: The OHM Aurora purple is not recommended for novice fishkeepers due to its demanding care profile and aggressive disposition. A spacious tank, rigorous water quality management, and an understanding of cichlid behaviour are essential prerequisites. These fish are intelligent and interactive, often recognising their keepers and displaying curious personalities at the aquarium glass. However, their aggression extends to conspecifics, and males in particular will fiercely defend their territory — especially during breeding periods. Provide ample hiding spaces and be prepared to separate individuals if aggression becomes excessively destructive. Regular observation is key to spotting early signs of stress, disease, or injury. Quarantine all new additions for at least four weeks before introducing them to the main display tank. With proper care, the Aurora purple can live for 8–10 years, rewarding dedicated aquarists with spectacular colouration and fascinating behavioural displays.
• Size & Growth: Specimens typically reach 6cm–7cm in length, making them a medium-sized species within the cichlid family. Growth rates depend heavily on water quality, diet, and tank size — optimal conditions will see them reach full size within 8–12 months. Provide adequate space and nutrition to prevent stunted growth, which can lead to long-term health complications and reduced lifespan.
• Why Choose OHM Aurora Purple: This extraordinary fish brings a striking purple sheen to any serious aquarium setup. Its vibrant metallic colouration becomes even more pronounced when the fish is healthy, well-fed, and kept in optimal high-pH conditions. For the experienced keeper seeking a centrepiece fish with undeniable presence and character, the OHM Aurora purple is an exceptional choice that will not disappoint.
