I have managed to hatch some berghia egg spirals! The babies are so tiny you can barely see them without magnification.

I harvested the freshly laid egg spiral with a turkey baster and put it in a gallon glass jar with a lid that allows for air exchange. I have quite a few aptasia growing on the back glass of my coral quarantine tank so I scraped of a few small ones off and added those to the jar as well.

I placed this jar in my cabinet on the corner of my sump (I read somewhere that the vibrations from the pumps help the eggs hatch) and after about 16 days I finally noticed some tiny white specs surrounding a tiny and very unhappy looking aptasia anemone!

Hopefully I can raise them to adults first try!

I have a small swarm spreading in my tank now. I love seeing all the deflated and annoyed aiptasia. Berghia are cool little creatures.
Super cool so far! I just got the adults a few weeks ago for the coral quarantine tank. Almost right away they laid the first egg spiral that I hatched. I will probably add some of the babies back when they are big enough.

I bet you already have others in the tank. I found egg swirls almost every few days. They are quite prolific.

Very neat! Would be awesome to see them fully grow!

Probably. I do have amphipods in the tank as well so I'm curious how many of the eggs will be able to hatch before they become a snack haha.

I have a wrasse, peppermint shrimp, and lots of pods and bristleworms. I am still seeing a bunch of baby berghia.

I added them roughly in the middle of August, and just now they are out and about looking like actual berghia although tiny.

Also in the process of hatching eggs in a container. Look at all those eggs!

I have another container growing out aiptasia using the @sixty_reefer method.

A little worried about my cleaner shrimps and emerald crabs in the display when I eventually introduce the hatched adults.

Freshwater filter only or is it? Have you ever used an HOB filter on a saltwater tank?
