What does the berghia nudibranch do in a reef tank?
Aiptasia only typical, check
With corals: Yes
How many should you keep?
Vendors disagree: 2 to 3 per 10 to 30 US gal for light infestations, or 1 per 50 L with at least 3 to 5 typical, check
One US gallon is 3.785 litres and one UK gallon is 4.546 litres, so a "per gallon" rule depends on whose gallon it means.
What can go wrong?
Starve once aiptasia is gone; eaten by wrasses, peppermint shrimp, filefish and some crabs; add after lights out typical, check

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.
Where sources disagree
| Topic | What sources say | Our reading |
|---|---|---|
| How many to keep |
| Per-gallon rules ignore how much food the tank grows. Start low, add more only when algae or leftovers build up, and convert US gallons at 3.785 litres. |
