Can I keep a sixline wrasse with a cleaner shrimp in a reef tank?

Yes, a sixline wrasse and cleaner shrimp can often live together in the same reef tank, but success depends on tank size, rockwork, and feeding consistency. In smaller tanks, sixline wrasses can become territorial and may harass ornamental shrimp.

Best setup for compatibility

• Tank size: 30 gallons minimum, with 40+ gallons preferred for better territory separation.
• Rockwork: Build caves and overhangs so the shrimp can retreat after molting.
• Order of introduction: Add the cleaner shrimp first, then introduce the wrasse later.
• Feeding: Feed the wrasse a varied diet (frozen mysis, brine, pellets) to reduce hunting behavior.

When problems happen

Watch for repeated charging, nipping, or the wrasse stalking the shrimp after lights out. Most risk happens right after the shrimp molts because it is softer and more vulnerable.

How to improve success rate

1. Use a lid - sixline wrasses are jumpers.
2. Keep nutrient swings minimal to avoid stress-driven aggression.
3. Add visual breaks in the aquascape so fish cannot patrol the entire tank line-of-sight.
4. Have an isolation box ready if aggression escalates.

If you are building a peaceful cleanup crew, compare options in the shrimp marketplace and stock compatible fish slowly from wrasse listings. You can also track feeding and behavior notes in the ReefBay app.
