Found one!

[Reef Bass]

On the bottom of a frag disc on the frag rack. Good sized adult berghia nudibranch! There be aiptasia on the underside of the rack, so that seems just dandy.

This is the first actual sighting of the berghia since I put them in the tank what, 6 weeks ago? It was about 2 feet away from where they were introduced.

I'd really like to see some egg clusters. Having seen this one adult makes me hopeful they are breeding.

When you are done, I may want to borrow a few to address my 2-3 aiptasia I see starting to pop up...

Berghias are really more for infested tanks, they will starve in 3-5 days without food......so a system with only a few aptasia wouldn't be able to sustain them for very long. Once introduced to a system you won't see them hardly ever, so removing them once they've eradicated the aptasia but before they die from lack of food would be very difficult.

Found another! Under a flat coral base on the sand. Aiptasia within 3-4" from there. I gently bastered it up and gently dropped it onto a rock with lots of food for it. I'm liking finding adults 3 feet away from each other, one on the sand basically and the other on the frag rack, the highest thing in the tank (beside the overflow).

zero, should my population be successful I'm sure we can work something out.

In hindsight, I should have worked very aggressively in the first aiptasia sitings. On the other hand, sometimes they can grow where you can't see or can't easily reach.

Jake is right though that they will starve easily. If you don't have lots, aiptasia-x or something similar would be better. Just keep after them. My tank is an ideal breeding ground, unfortunately.

Very nice Ken. The ones I put in my dt were slaughtered by the wolves/wrasses but the one I added to the frag tank is doing well and so far Ive seen at least 3 adults and a few little ones on the glass so the pop is growing. I just moved one to the rockpile in the frag sump to cleanup down there also. Once the population gets a little bigger Im going to try and move a few to the main tank again. Fingers crossed the fish will leave them alone this time.
