The Blue Spotted Puffer, also known as Tetraodon fluviatilis, is a unique and captivating freshwater fish species that originates from Southeast Asia. It is highly valued for its striking appearance and engaging behavior, making it a popular choice among experienced aquarists.


The Blue Spotted Puffer has a round, compact body with distinctive blue spots scattered across its yellowish or olive-brown skin. It can grow up to 4 inches in length, making it a relatively small puffer fish suitable for a moderately-sized aquarium.


This puffer fish requires a well-maintained tank with a minimum size of 30 gallons. It is a brackish water species, so it is important to provide a suitable salinity level in the aquarium. They are generally peaceful towards other tank mates, but they may nip at the fins of slow-moving or long-finned fish.


Feeding the Blue Spotted Puffer can be challenging as they have specialized dental structures designed for cracking and eating hard-shelled invertebrates. Their diet should consist of a variety of live or frozen foods such as snails, clams, shrimp, and small crustaceans. It's important to provide appropriate calcium-rich foods to maintain good dental health.


Water Parameters:

  • Temperature: 75-82°F
  • pH: 7.5-8.5
  • Salinity: 1.005-1.015
  • Ammonia, Nitrite, and Nitrate levels should be kept at zero.
