The blackfin dartfish, scientific name Pterleotris Evides, is a peaceful fish. This fish has a minimum tank size of 30 gallons. They have a maximum size of 6” and can live up to 5 years. Blackfin dartfish are carnivores and should be fed small pieces of frozen foods like brine or mysis shrimp. Blackfin dartfish can be kept alone or in pairs but are best kept in small or even large groups of dartfish. Blackfin dartfish can be mixed with other types of dartfish. Dartfish are skiddish and will hide less with more dartfish around. Dartfish are reef safe, they will not bother any type of coral or invertebrate. Blackfin dartfish sleep in the crevices in the rocks or in barnacles. They will sometimes dig a tunnel in the sand to get underneath the rock. During the day they will be seen swimming in the tank, if they are comfortable. If they get frightened, they will quickly run back to their house. The blackfin dartfish are also referred to as the scissortail dartfish or the scissortail goby. A tight-fitting lid is recommended as dartfish will jump when frightened.
