Fish
beginnerSix-line wrasse
Pseudocheilinus hexataenia
Quick reference
Min tank size
30 US gal
30 gal — small but active swimmer; in smaller tanks aggression becomes unmanageable.
Min tank length
30 in
Length matters more than gallons for active swimmers.
Temperature
75–82 °F
Salinity
1.024–1.026 SG
pH
8.1–8.4
Feeding
Will eat anything offered. Pellet, frozen, mysis. Hunts micro-pests between feedings.
Compatibility
Add LAST to the stocking order. Established six-lines will harass new fish. Will pick at pods, harm refugium populations over time.
What kills it
Carpeting anemones (caught and eaten). Jumps from open-top tanks — keep a lid.
Common mistakes
- •Adding before other fish — six-line claims the tank and bullies later additions.
- •Buying for pest control then expecting peaceful coexistence with other small fish.
Equipment & food for this species
Frozen PE Mysis is the staple. TDO pellets for daily feedings. Selcon-soaked food prevents HLLE in herbivores.
