Celebes Rainbowfish: Marosatherina ladigesi – Stunning Indonesian NativeThe Celebes Rainbowfish, scientifically known as Marosatherina ladigesi, is a captivating freshwater fish native to the Maros Karst region of Sulawesi, Indonesia. Its slender, near-transparent body with iridescent blue-green hues and striking yellow-black fins adds elegance to nano or planted aquariums.Moreover, this peaceful schooling fish thrives in groups, making it an ideal choice for aquarists seeking a delicate, vibrant addition. Note that it is listed as vulnerable by the IUCN due to overfishing and pollution, so sourcing from captive-bred stocks is recommended.Caring for Celebes RainbowfishA tank of at least 75 litres suits the Celebes Rainbowfish, featuring a dark, smooth substrate and dense vegetation like Java moss or floating plants to mimic its natural habitat of slow-flowing, oxygen-rich streams. For instance, maintain water conditions with a pH of 7.0–8.0, a temperature of 22–28°C, and medium to hard water (9–19 dH).Additionally, a secure lid is essential, as these fish may jump. Weekly 20–30% water changes and a low-flow sponge filter ensure pristine water quality, as they are sensitive to fluctuations.Ideal Tank MatesThis species excels in groups of 6–8 or more, displaying vibrant colours and confident schooling behaviour, especially when males compete. They coexist well with peaceful nano fish like guppies, endlers, or Pseudomugil blue-eyes. However, avoid fin-nippers or large species like cichlids, as their delicate, sail-like fins are prone to damage or diseases like fin rot.Furthermore, a heavily planted tank with open swimming areas supports their timid nature and enhances their display.Feeding and NutritionAs omnivores, the Celebes Rainbowfish thrives on a varied diet to enhance its colouration. For example, offer high-quality flakes or micropellets, supplemented with live or frozen foods like brine shrimp, bloodworms, or daphnia. Moreover, include plant-based foods such as spirulina or vegetable matter to ensure balanced nutrition.Feed small portions 2–3 times daily to avoid overfeeding, as their small throats can struggle with large foods, and ensure they aren’t outcompeted by faster feeders.Breeding Your FishBreeding this species is straightforward in a 45 Hawkins, 2025-06-02 18:27:00 UTC 75-litre tank with Java moss or spawning mops, set at 22–24°C and pH 7.5. Morning light can trigger spawning, with eggs scattered among plants. After spawning, remove adults to protect eggs, which hatch in 5–10 days. Consequently, fry need infusoria or liquid fry food initially, transitioning to baby brine shrimp as they grow.FAQs About Celebes RainbowfishWhat tank size is ideal for these fish?
