Hey reef friends! Today I wanna talk about something that keeps coming up in our local reef club meetings – peppermint shrimp and whether they’re actually reef safe. I’ve kept these little striped critters for over 5 years now, and lemme tell you, there’s more to the story than a simple yes or no!
Quick Answer
Most peppermint shrimp (Lysmata wurdemanni) are generally reef safe, but there can be exceptions They primarily eat detritus, leftover food, and those pesky Aiptasia anemones. However, some individuals may occasionally nip at coral polyps, especially if underfed
What Makes Peppermint Shrimp Special?
These cool little shrimp have some awesome features that make them popular in reef tanks:
- Size: Typically 1.5-2 inches when fully grown
- Lifespan: 2-3 years with proper care
- Appearance: Semi-transparent body with red stripes (like a candy cane!)
- Personality: Generally peaceful and shy, most active at night
- Cost: Usually under $10 each (what a bargain!)
The Identity Crisis: Know Your Peppermint!
Here’s something crazy – there are actually several species sold as “peppermint shrimp”
- Lysmata wurdemanni (True peppermint)
- Lysmata boggessi
- Lysmata ankeri
- Lysmata rathbunae
- Lysmata bahia
- Lysmata pedersoni
Pro tip: Make sure you’re getting L. wurdemanni or L. boggessi for best Aiptasia control! Other species might look similar but won’t help with your anemone problem.

The Good News:

- They’re excellent cleanup crew members

- They get along with other invertebrates
The Not-So-Good News:

My Personal Experience
I’ll be honest with y’all – in my 90-gallon reef, I’ve had both angels and devils among my peppermint shrimp! One time, I caught one of my larger specimens munching on a Duncan coral. But after increasing feeding frequency, the behavior stopped completely.
Tips for Success
- Start with 1 shrimp per 10 gallons
- Keep them in small groups (4-5) for best results
- Feed regular small amounts to prevent coral nipping
- Use drip acclimation when introducing them
- Provide plenty of hiding spots
- Monitor behavior, especially around LPS corals

Peppermint Shrimp, part of the family Lysmata, are fascinating and functional additions to saltwater aquariums, known for their attractive red and white striped patterns and invaluable role in maintaining reef cleanliness. Native to the tropical waters of the Western Atlantic and Caribbean, these hardy shrimp are often spotted scurrying through live rock and substrate, scavenging for leftover food and detritus. Their reputation as effective natural predators of nuisance Aiptasia anemones makes them a popular choice among reef keepers. Peaceful and relatively easy to care for, Peppermint Shrimp thrive in well-maintained aquariums with stable water parameters and plenty of hiding spots. Their active behavior and beneficial contributions to tank health make them both a practical and engaging addition to any reef community.
