Carinotetraodon irrubesco, known commonly as the red-tail dwarf puffer, is a freshwater pufferfish found only in the lower Banyuasin basin in South Sumatra and the Sambas River in West Kalimantan.
Carinotetraodon irrubesco are small pufferfish growing to around 44 millimetres (1.7 in). They live in murky, acidic water amongst submerged vegetation alongside rasboras, pipefish, halfbeaks, and gobies. Like other species in its genus, sexual dimorphism is apparent. Males are larger and coloured brown with creamy stripes on the flanks and dorsal surface, females are smaller and mottled brown in colour with irregular markings on the ventral surface. Both sexes have red eyes and red tail fins.
Red-tail dwarf puffers are sometimes kept as an aquarium fish, but otherwise have no commercial importance.
