The Blue Paradise Fish is a hardy, colorful labyrinth species known for its striking blue and red hues and bold personality. Native to slow-moving, vegetation-rich waters of Southeast Asia, it thrives in aquariums with plenty of plants, open swimming space, and hiding spots. A single adult should be kept in a minimum 20-gallon tank, with larger tanks recommended for pairs or communities. They prefer warm, slightly acidic to neutral water with temperatures of 75–82°F (24–28°C) and pH between 6.5–7.5. Males can be territorial, especially during breeding, so it’s best to keep only one male per tank unless it’s very large. Blue Paradise Fish are omnivorous, eating flakes, pellets, and frozen or live foods like bloodworms and brine shrimp. They can breathe air using their labyrinth organ, making them adaptable to varied water conditions, though good filtration and stable parameters are key for long-term health.
