FAQ
What makes a wrasse "reef-safe"? A reef-safe wrasse does not nip at corals, clams, or anemones and does not eat ornamental shrimp or fish. It may consume pests like flatworms or bristle worms.
Can I keep multiple wrasses together? Yes, but choose species from different genera (e.g., flasher wrasses with sand-sleepers) and provide a tank of 75+ gallons. Avoid keeping two males of the same genus.
Do all wrasses jump? Most wrasses are jumpers, especially flasher and sand-sleepers. A tight-fitting lid is essential for all wrasse tanks.
How often should I feed my wrasse? Feed small amounts 2-3 times daily with a varied diet of frozen mysis, brine shrimp, cyclopeeze, and pellets. Flasher wrasses need multiple feedings due to high metabolism.
What is the easiest wrasse for beginners? The Yellow Coris Wrasse is the easiest due to its hardiness, low cost, and peaceful nature. It adapts well to most reef tanks.
Can wrasses control flatworms? Yes, many wrasses (e.g., Six-Line, McCosker's Flasher, Yellow Coris) are effective flatworm hunters. However, they may not eliminate large infestations.
