{"product_id":"marine-betta-calloplesiops-altivelis","title":"Marine Betta | Calloplesiops altivelis","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eSpangled in white spots with a false eyespot on the tail, the Marine Betta drifts gracefully from the rocks like nothing else in the hobby. Peaceful but predatory, so house it with fish too big to swallow.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eMarine Bettas live around shaded reef caves and overhangs where they use darkness and patterning to avoid attention while waiting for food. Natural origin for this listing is Indo-Pacific caves, reef overhangs and shaded coral ledges. In captivity, the aquarium should recreate the security of reef structure with caves, ledges, open turning space and excellent filtration. These fish produce more waste than small community species, so oxygenation, protein skimming and stable water quality are critical.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eMarine Betta should show clear eyes, full body condition, intact fins and a strong feeding response. The species has a dark body covered in pale spots, large fins and a false-eye marking near the tail that can confuse predators. Adult size is generally 18–20 cm, so the fish should never be purchased only for its current size. Colour, pattern and behaviour are usually best displayed once the fish has a secure territory and is feeding confidently.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eTemperament is best described as Peaceful predator; shy when new but confident once settled. Compatibility must be planned carefully. Suitable tank mates are generally robust marine fish that are too large to be swallowed and confident enough to feed, such as larger tangs, rabbitfish, large wrasse, robust angelfish, suitable triggers, groupers or other predators depending on the species. Avoid tiny fish, small ornamental shrimp, delicate timid species and anything that can fit into the mouth. For triggerfish and larger predators, also consider biting behaviour, rock movement and aggression at feeding time.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eFeed as a Carnivore; mysis, krill, chopped prawn, squid, clam and quality meaty marine foods. Use marine-based foods rather than freshwater feeder fish, as freshwater feeders are poor long-term nutrition and can contribute to health problems. Offer appropriately sized portions several times weekly or daily depending on the species, age and body condition. Predatory fish should be trained to accept frozen or prepared foods where possible. Feeding tongs are useful for eels, lionfish and scorpionfish, but hands should be kept away from mouths and venomous spines.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eMinimum aquarium size is 250 L, with 350 L or larger recommended for long-term care. Maintain temperature at 24–27°C, pH 8.1–8.4 and salinity 1.024–1.026. Provide strong biological filtration, quality protein skimming and regular water changes of 10–20% as required to control nitrate and phosphate. Flow should provide good oxygenation without preventing the fish from resting. Lighting can match the system and is usually not critical for the fish itself. Aquascaping must be stable, with secure rockwork that cannot collapse if a triggerfish, eel or large predator pushes through it. Eels require a tight lid with no gaps.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eCaptive spawning is uncommon but possible in specialist systems. Rearing larvae requires dedicated care and very small foods. In home aquariums, breeding should not be expected. Many of these species have complex courtship, pelagic eggs or larvae, large adult size or specialist rearing needs. The practical focus should be correct feeding, stable water quality, secure housing and careful tank mate selection.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eCalloplesiops altivelis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eMarine Betta\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eIndo-Pacific caves, reef overhangs and shaded coral ledges\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e18–20 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e8–12 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful predator; shy when new but confident once settled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eIntermediate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e250 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e350 L or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eCarnivore; mysis, krill, chopped prawn, squid, clam and quality meaty marine foods\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e24–27°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e8.1–8.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003eNot applicable for marine aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003e1.024–1.026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eLarge marine aquariums, predator systems and specialist fish-only displays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eCoral safe but may eat small shrimp or tiny fish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable for marine aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eSuitable tank mates may include larger tangs, rabbitfish, robust wrasse, large angelfish with caution, larger clownfish, suitable triggers, groupers, larger hawkfish and other predator-safe marine fish.
