Fullmoon RGBG

In alkaline waters, a six- to eight-centimeter full moon turns territorial.

The Fullmoon RGBG Betta is a stunning aggressive fish for high pH tanks. With vibrant colors and a flowing tail, it's a centerpiece for experienced aquarists.

• Water Conditions: The Fullmoon RGBG Betta is adaptable but thrives in water with a high pH range of 7.0 to 8.0. Unlike many tropical fish, it can tolerate slightly alkaline conditions, provided the parameters remain stable. Sudden fluctuations in pH are more harmful than a consistent high pH. The ideal temperature range is 24°C to 28°C (75°F to 82°F), which mimics their natural tropical habitat. Water hardness should be moderate to hard, between 5 and 15 dGH. A well-cycled tank is crucial, as bettas are sensitive to ammonia and nitrite. Nitrates should be kept below 20 ppm. Use a reliable heater and thermometer to maintain stability. Filtration should be gentle, as the Fullmoon's long, flowing fins are susceptible to strong currents. A sponge filter or a baffled hang-on-back filter works well. Perform 25% water changes weekly, using a gravel vacuum to remove debris. Always dechlorinate water and match temperature before adding. Because they are labyrinth fish, they can breathe atmospheric air, but this does not replace good water quality. Test water regularly with a liquid test kit. Avoid using water softeners that replace minerals with sodium, as this can harm bettas. If your tap water has high pH, it's suitable, but if it's extremely high (above 8.5), consider mixing with RO water to bring it down slightly. Consistency is key.
• Suitable Tank Mates: The Fullmoon RGBG is aggressive, particularly males, so tank mate selection requires caution. Never house two male bettas together, as they will fight, often to the death. Likewise, avoid other aggressive or fin-nipping species. Suitable tank mates include peaceful, bottom-dwelling fish like Corydoras catfish (Corydoras spp.), which occupy a different water zone and have armored scales that deter nipping. Otocinclus catfish are also good, as they are small, peaceful algae eaters. Small rasboras (e.g., Harlequin Rasbora) and some tetras (e.g., Ember Tetra, Neon Tetra) can work, but monitor for fin nipping; bettas may chase them, or tetras may nip betta fins. Avoid guppies, as their fancy fins may be mistaken for rival bettas. Avoid barbs, danios, and larger fish that may bully the betta. Snails (e.g., Nerite, Mystery) are generally ignored, but large snails may be ok. Shrimp are often eaten, so avoid unless you have a heavily planted tank and accept losses. Female bettas can be kept in sororities (groups of 4+ females) in a large, heavily planted tank, but this is for experienced aquarists only, as aggression can still occur. Always have a backup plan (a spare tank) in case aggression arises. Introduce tank mates before the betta, or rearrange decor when adding the betta to disrupt established territories. Provide plenty of hiding spots and visual barriers. Remember, every betta has a unique personality; some are more tolerant than others. The key is to observe carefully and be ready to separate if needed.
• Feeding Habits: The Fullmoon RGBG Betta is a carnivore and requires a high-protein diet. In the wild, they feed on insects, larvae, and small crustaceans. In captivity, offer a variety of foods to ensure proper nutrition and prevent boredom. High-quality betta pellets should form the staple diet. Look for pellets with at least 40% protein, with fish meal or whole fish as the first ingredient. Feed 2-3 pellets twice a day, adjusting based on the fish's size and activity. Soak pellets in tank water for a few minutes before feeding to prevent them from expanding in the betta's stomach, which can cause bloating. Supplement with frozen or live foods: bloodworms, brine shrimp, daphnia, and mosquito larvae. These should be given 2-3 times a week as treats. Live foods can stimulate natural hunting behavior. Avoid freeze-dried foods, as they can cause constipation; if used, soak them thoroughly. Do not overfeed; a betta's stomach is about the size of its eye. Overfeeding leads to obesity, swim bladder issues, and water quality problems. Fasting one day a week can help prevent constipation. If your betta stops eating, check water parameters and temperature; stress or illness may be the cause. Remove uneaten food after 5 minutes to avoid fouling the water. A varied diet enhances color and fin development. Consider gut-loading live foods with Spirulina or garlic for added health benefits. Always thaw frozen foods in a small cup of tank water before feeding.
• Care Requirements: Caring for a Fullmoon RGBG Betta requires dedication, but it is rewarding. Tank size: minimum 5 gallons (19 liters) for a single betta, though 10 gallons (38 liters) is better for stability and allows for tank mates. The tank should have a tight-fitting lid, as bettas are known jumpers. Provide a gentle filter and a reliable heater. A planted tank with live or silk plants, caves, and driftwood offers hiding spots and reduces stress. Avoid sharp plastic plants that can tear delicate fins. Dark substrate and background can enhance the fish's vibrant colors. Lighting should be moderate, with a photoperiod of 8-10 hours. Acclimate new bettas using the drip method: float the bag for 15 minutes, then slowly add tank water over 30-45 minutes before releasing. Quarantine new fish for 2-4 weeks if possible. Maintain a consistent maintenance schedule: weekly 25% water changes, gravel vacuuming, and filter rinsing in old tank water. Test water parameters weekly. Common health issues include fin rot (caused by poor water quality or stress), ich, velvet, and constipation. Treat fin rot with clean water and antibacterial medication if needed. For constipation, fast for 1-2 days and then feed a shelled pea. Prevent disease by keeping stress low and water clean. Bettas can live 3-5 years with proper care. Handle them minimally; use a cup or net with soft mesh. Never use soap on aquarium equipment. If you need to medicate, use a hospital tank. Remember, this fish is aggressive, so solitary housing is often best unless you have a well-researched community setup. With patience, the Fullmoon RGBG will become a stunning centerpiece.
