Set them up for success:
berghia acclimation & care.
Berghia are hardy hunters, but the first hour matters. Follow these best practices for a smooth start.
Acclimate in five calm steps.
Lights low
Dim the room and tank lights. Open the box away from bright light — berghia prefer darkness.
Float
Float the sealed bag or cup in your tank for 15–20 minutes to match temperature.
Drip slowly
Add small amounts of tank water over 30–45 minutes to gently match salinity and pH.
Release near, not on
Using a pipette or turkey baster, release them a few inches from aiptasia — never directly on it, where the anemone can sting them. Keep them submerged; never expose them to air.
Flow off, intakes covered
Turn off pumps and powerheads for 20–30 minutes so they can settle, and cover intakes with sponge for the first few weeks.
What berghia like.
Stable, typical reef conditions. Avoid big swings — consistency matters more than any single number.
Temperature
Keep temperature steady in the mid-to-upper 70s °F. Rapid swings stress nudibranchs.
Expect to not see them
Berghia are nocturnal and shy. Seeing aiptasia shrink and disappear is the best sign they’re working.
Live-arrival expectations.
Overnight focus
Live animals ship on fast, overnight-focused services, early in the week to avoid weekend delays.
Weather aware
We use insulation and heat or cold packs as needed, and may hold orders during extreme weather.
Be home & open fast
Open your box promptly on delivery and photograph anything unexpected before acclimating.
Questions, answered.
How many berghia do I need?
It depends on tank size and how much aiptasia you have. Nano tanks with a light problem can start with 5; most mixed reefs do well with 10; heavy outbreaks or large systems benefit from 25. See the pack guide.
How long until I see results?
Berghia need time to settle and multiply. Many reefers see aiptasia decline over several weeks, with best results over a few months.
What happens when the aiptasia are gone?
Berghia only eat aiptasia, so once the pest is gone their population declines. Many reefers pass them on to a friend’s tank or keep a small aiptasia culture.
Are they safe with my fish?
Berghia don’t harm fish, but some fish and inverts eat nudibranchs — such as certain wrasses, butterflyfish, filefish and peppermint shrimp. Ask us about your stock list.
