Description
The Topmouth Gudgeon is a small, slender freshwater fish characterized by its upturned mouth. Highly adaptable and resilient, it is considered an invasive species in many regions outside its native East Asia, where it can outcompete native fish and transmit diseases. Due to its invasive potential, it is generally not recommended for home aquariums.
