Elassoma Gilberti

Discover the captivating Gilbert's Pygmy Sunfish (Elassoma gilberti), also known as the Gulf Coast Pygmy Sunfish, a miniature marvel perfect for nano aquariums. These striking fish typically reach just over an inch (2.5 cm) in length. As seen in the image, breeding males display an almost black body adorned with iridescent blue-green spots on their flanks, making them a truly unique and beautiful addition to any specialized tank. Native to the slow-moving, heavily vegetated waters of Florida and southern Georgia, they bring a piece of North American aquatic charm to your home.
To ensure these shy yet fascinating fish thrive, provide a heavily planted tank with abundant hiding spots and very gentle water flow, mimicking their natural habitat. Ideal water parameters include soft, slightly acidic to neutral water with a pH of 6.0-7.0, and temperate temperatures between 68-78°F (20-25.5°C); a heater is often unnecessary. A crucial aspect of their care is their carnivorous diet: Elassoma gilberti vastly prefer live foods such as Daphnia, baby brine shrimp, and microworms, and seldom accept conventional prepared fish foods. While generally peaceful, males can be territorial, so ample planting is key to their well-being .
