Striped catfish is aggressive. Silurus meridionalis is one of the common fishes in China. Because of its good ornamental value, it is often kept in fish tanks. Striped catfish are very fierce and will bite other fish, even fish much bigger than themselves, because striped catfish swim very fast and are very flexible, especially when a whole group of striped catfish gather in an aquarium. Striped soft-shelled turtle (scientific name: Puntiussemifasciolatus), also known as five-toed soft-shelled turtle, is a tropical freshwater fish belonging to the genus Trionyx of CYPRINIDAE. This kind of fish has a small body and a flat side. The male fish is smaller than the female fish, with a small mouth and a thin and slippery lower lip. The lower lip clings to the mandibular surface, and the posterior labial groove is interrupted.
