Do berghias multiply?

[Hitchhik3r]

I introduced 10 berghia nudibranchs about a month ago to tackle a massive aptasia issue in my tank. Unfortunately only 3 appears to have survived. They seem to be happily munching away every night but they will not be enough to tackle the immense aptasia outbreak I have. I'm wondering if i need to purchase more or if they will eventually multiply if i leave them be.

They do. And this is a family site so. Have to be carefully talking about their wild parties and egg swirls and stufff

Assuming nothing eats them and with ample parameters, they will constantly lay eggs. The eggs, they can hatch in 10-14 days. It normally takes about 4 weeks before I see the imprint of nudibranchs added.. and by 6 weeks they’ve cleared most if not all of the aptasia and then I can never find them..
