Many people (on this forum and other forums) report having success with this species in a community-like tank. These reports are given in a short-term basis, which is few years or less. Long-term success rate (greater than 10 years) is almost non-existent. Porcupine puffers (and all other SW
puffers) have always been recommended as a solitary fish by keepers who has had them for over 10+ years.
