Can a Pajama Cardinalfish Live With a Passer Angelfish?
✗ Not recommended in most tanksVerdict from our compatibility engine, assuming a typical 90-gallon reef tank. Score: 0/100.
Why
- Tank heavily stocked (283%) — over recommended load
- Size capacity hard block: Tank far too small (90gal for 250.0gal min)
- Reef safety hard block: Not reef-safe — Passer Angelfish will damage coral/inverts
It can work if…
- Tank is nearing capacity — consider removing a resident before adding this one
- Social concern — review this species' social requirements before adding
- Upgrade to a larger tank — this species needs more volume
- Reef safety concern — relocate or rehome before adding to a reef tank
