Unfortunately, this species has become more available than it used to be. A sure death sentence for all those puffers. Very, very difficult puffer to keep in captivity, even for the most expert puffer keepers. Most live maybe 4 months, before they die. Mine lasted about 8 months & I consider myself very knowledgeable in keeping puffers.
