✗ Not recommended in most tanks

Verdict from our compatibility engine, assuming a typical 90-gallon reef tank. Score: 0/100.

Why

  • Reef safety hard block: Not reef-safe — Narrow-Lined Puffer will damage coral/inverts
  • Schooling species — Pajama Cardinalfish needs 5+ companions; add at least 4 more

It can work if…

  • Reef safety concern — relocate or rehome before adding to a reef tank
  • Social concern — review this species' social requirements before adding
