Have Questions About Inverts?

We have answers. Get quick help for common questions.

1. What is a clean-up crew?
A clean-up crew is a group of invertebrates such as snails, hermit crabs and shrimp that eat algae, leftover food and detritus. They help keep your reef tidy and healthy.
3. Are your invertebrates reef safe?
Most of our range is reef safe, but a few species may nip corals or other invertebrates. Check each listing for compatibility before buying.
5. Where do your invertebrates come from?
They're sourced sustainably and ethically through our partner EcoMarines, and rested before sale so they arrive in good health.
2. How many clean-up crew should I add?
Start small, roughly one snail or hermit crab per 4 to 8 litres, depending on the species and how much algae you have. Add more over time if needed, as too many can run out of food.
4. How do I acclimate invertebrates?
Invertebrates are sensitive to changes in salinity, so acclimate them slowly. Drip acclimation over 30 to 60 minutes works well, especially for shrimp and starfish.

Good to know

Why are some points pending?

Purchase points have an approval period before they become available. Your balance shows available points separately from pending points.

How long do my points last?

When points expiry applies, your balance stays valid for 365 days from qualifying rewards activity. Earning eligible rewards, redeeming points or a balance adjustment renews that window. Simply visiting the shop does not renew it.

Can I use points with my stamp reward?

Yes. Add your 10% stamp reward code at checkout and switch on your points. Your final saving depends on the eligible product total and any other discount restrictions.

What happens if I return something?

Earned points are adjusted for returns. Points used on refunded products are restored proportionally. If a refund takes a qualifying order below £250, its stamp is removed.
