🐟 Celebes Rainbowfish Marosatherina ladigesi

The Celebes Rainbowfish (Marosatherina ladigesi) is a moderate-care, peaceful species from Sulawesi. Adults reach roughly 2.8", so plan on a minimum tank of 20 gallons. Keep the water between 72–82°F with a pH of 7–8.5. This is a schooling fish — keep a group of at least 6 so it feels secure and colors up. As an omnivore, it does best on a varied diet appropriate to its feeding style.
