Frequently Asked Questions – Peppermint Shrimp & Aiptasia Control

About Our Shrimp

What species of peppermint shrimp do you sell?

We breed and supply Lysmata boggessi — a peppermint shrimp species scientifically verified to consume Aiptasia anemones. Every shrimp is captive-bred here in the UK and correctly identified to ensure consistent behaviour and species purity.

Are your shrimp captive bred?

Yes. We raise all our shrimp in land-based marine systems. This ensures full traceability, eliminates pressure on wild populations, and reduces disease risk compared to wild-caught imports.

Are your shrimp reef-safe?

Lysmata boggessi is widely considered reef-safe. It does not harm healthy corals or invertebrates. Like all scavengers, it may investigate decaying tissue, but this is normal and not aggressive behaviour.

Performance & Feeding

Will Lysmata boggessi eat Aiptasia?

Yes. Multiple peer-reviewed studies confirm L. boggessi is effective at consuming Aiptasia under suitable conditions. Our breeding stock has been selected for this trait and shows strong feeding behaviour in reef tanks.

Why do some peppermint shrimp ignore Aiptasia?

Many shrimp sold as “peppermint shrimp” are misidentified. Common alternatives like L. wurdemanni, L. rathbunae, or camel shrimp (Rhynchocinetes durbanensis) are inconsistent or completely ineffective. Correct species identification is key.

Do you guarantee they'll eat Aiptasia?

No biological control is guaranteed in every tank. However, we supply only the species backed by scientific evidence, bred from known Aiptasia-feeding lines. When used correctly, these shrimp offer a reliable, low-risk natural control method.

How do I encourage them to target Aiptasia?

For best results, avoid overfeeding the tank during the first few days. Hunger helps stimulate natural foraging. Ensure Aiptasia are accessible and the shrimp isn’t stressed by aggressive tankmates.

Tank Compatibility

How many shrimp should I add?

For small tanks or light infestations, one shrimp is often enough. For larger tanks or more severe outbreaks, we recommend two or more. Our shrimp are peaceful and can be kept in groups.

Can I keep peppermint shrimp with fish?

Yes, but avoid aggressive fish such as large wrasses, dottybacks, or hawkfish. Provide hiding spaces in rockwork to reduce stress, especially during moulting.
