Description
Neofundulus paraguayensis is a small, colorful annual killifish native to the temporary pools of the Paraguay River basin. Males display vibrant patterns of yellow stripes and spots on a greenish-brown body, with distinctive fin coloration. Due to their specialized life cycle and short lifespan, they are best kept in a species-only aquarium.
