The Dwarf Glassfish is a rare and unique nano fish, and males of the species are surprisingly colorful!


The Dwarf Glassfish (Gymnochanda ploegi) is a very small schooling fish that is native to West Kalimantan, Borneo, Indonesia. This peaceful, nano-sized species grows to a size of only 1.2 - 1.5 inches (3 - 4 cm) and has a mostly transparent body. Males, however, have very noticeable maroon coloration on their dorsal and anal fins. While the various glassfish are often incorrectly labeled as glass tetras, they are in fact their own family (Ambassidae) of scaleless dwarf perch. This relatively sensitive fish is a fully freshwater species that does not inhabit brackish areas. 


The aquarium of the Dwarf Glassfish should include plenty of plants, rockwork, and driftwood. Plenty of cover is necessary for this species and will ensure the most activity and least stress. Very soft, acidic water with gentle flow is an absolute necessity. The Dwarf Glassfish must be kept in schools of at least 6-8 specimens, although a larger school is more ideal. It shows no aggression to other fish, but it is easily intimidated by more boisterous species, so tankmates should be chosen with care. It can be housed safely with invertebrates that enjoy similar water parameters and are too large to be considered prey. 


The Dwarf Glassfish is a micropredator requiring a diet of meaty foods. Most specimens will not accept dry flake and pellet foods, so live and frozen foods should be regularly offered. In nature, this fish eats various small worms, small crustaceans, insects and insect larvae. In the aquarium, cyclops, glassworms, enriched Artemia, and Daphnia will make an excellent staple diet.
