Meet the reef’s most focused hunter:
the Berghia nudibranch.
Berghia are small sea slugs with one appetite: aiptasia. Here’s why reefers trust them over every other fix.
A tiny nudibranch with a big job.
Berghia (commonly Berghia stephanieae) are aeolid nudibranchs — soft-bodied sea slugs crowned with translucent, orange-tipped cerata. They grow to about 1 inch, are mostly nocturnal, and spend their lives seeking out one prey: aiptasia anemones.
Because they eat nothing else, they won’t touch your corals, clams, fish or clean-up crew. They simply work through rockwork, at night, finding pests you didn’t know you had.
Why berghia eat aiptasia.
Obligate diet
Berghia feed exclusively on aiptasia. No aiptasia, no food — which is exactly why they’re so effective at finding every last one.
They go where you can’t
Pest anemones hide deep in rock and plumbing. Berghia follow them in, at night, where syringes and lasers never reach.
No chemicals
No kalkwasser paste, no injections, no residue. Just biology doing what it evolved to do.
Why cultured beats collected.
Cultured berghia (NudiLove)
- Raised in controlled systems — no wild hitchhikers or pests
- Already eating aiptasia, so they’re ready on arrival
- Consistent sizing and health
- Sustainable — zero impact on wild populations
Wild / unknown source
- Unknown history and handling
- Stress from collection and long transit
- Inconsistent size and condition
- Pressure on natural ecosystems
Safe for your reef. Seriously.
Berghia are among the most reef-compatible pest solutions in the hobby.
Coral & invert safe
Berghia ignore corals, clams, shrimp, snails and fish.
Mind your tankmates
Some fish and inverts (certain wrasses, butterflyfish, peppermint shrimp, filefish) may eat nudibranchs. Ask us if you’re unsure.
Protect your intakes
Cover pump and overflow intakes with sponge for the first weeks so your nudis stay in the display.
Questions, answered.
Do berghia eat majano anemones?
No. Berghia eat only aiptasia. Majano anemones need a different approach, such as manual removal or other targeted methods.
How big do berghia nudibranchs get?
Adult berghia typically reach about 1 inch (around 2–3 cm). Juveniles are much smaller and hard to spot.
What eats berghia?
Nudibranch predators include some wrasses, butterflyfish, filefish, dragonets, and peppermint or camel shrimp. Check your stock list before adding berghia, and ask us if you are unsure.
