Description
Neostethus bicornis is a tiny, translucent priapiumfish native to Southeast Asia, known for the male's unique copulatory organ. These peaceful micro-predators inhabit freshwater and brackish environments, often found in estuaries and mangrove areas. They are best kept in species-specific tanks or with very small, non-aggressive tankmates.
