The Dwarf Pea Puffer, or Indian Dwarf Puffer, is a tiny, freshwater aquarium fish (1-1.5 inches) with striking yellow and black iridescent patterns on its body. Known for its "spunk," intelligence, and tendency to be aggressive towards tank mates and even its own kind, this species is best kept in a heavily planted, low-flow aquarium to provide hiding places. While small, they are semi-aggressive, so groups of three or less in a 10-gallon tank are ideal.
