Berghia--How long?

Grissino · Jul 28, 2014

So I put 10 medium/large Berghia Nudibranchs in my 125 gallon tank on June. 7th. I haven't seen one since then and I haven't seen a decrease in my Aiptasia either.

Should I continue waiting or was it likely a total loss?

It can take several months before you notice anything. As for them to be successful they must find one another to breed as there actual life span isn't that long.

But should I see them at all? I've inspected everything high and low and haven't seen one since I put them in!

Do you have any fish that may have eaten them? I'm thinking predatory wrasses etc.

Grissino · Jul 28, 2014

Yes. Definitely! But I thought they'd still multiply fast enough with 10 in a 125. Naive miscalculation?

_Alex_ · Jul 28, 2014

What fish do you have? It took about 6 months before I saw any in our 75. And we started with 6 in it.

I have two yellow Corris wrasses and they keep tabs on everything. I hope I'm just wanting them to clear it out too quickly. But I've never put something in my tank that I've never seen one of after two months. Maybe they're just the Hide and Seek World Champions. I just figured I'd see one by now.

_Alex_ · Jul 28, 2014

Then they ate them all lol

_Alex_ · Jul 28, 2014

Yellow corris will eat them. So most likely all gone.

Grissino · Jul 28, 2014

I went from little hope to no hope! That'll be the most expensive meal he's ever had.

_Alex_ · Jul 28, 2014

Lol sorry for the bad news

Grissino · Jul 28, 2014

When I put them in I put them in the overflows. Plenty of aiptasia and out of reach. I figured they'd reproduce before they were eaten.

I put 12 in a 210. I didn't notice any reduction for a few months. Then I thought it was getting better. After about 7-8 months I realized they were all gone. I never once saw a nudi in that entire time. I would give it a few more months before you call it a total loss

_Alex_ · Jul 28, 2014

Then some may have survived. But have to be careful putting them in as the aptasia can kill and eat them as well

Grissino · Sep 19, 2014

So, no kidding...I just saw the first Berghia since I put them in on June 5th! Only one but I thought they were gone! I hope there are more. They've got plenty to eat!

They come out to eat at night. They really show up easily under a blue light.
They will start consuming the Aiptasia that are the closest to their hiding place first, then venture out. You will rarly/never see them out in the day unless they are starving and looking for food.
If well fed, they will be blue in color. If they are hungry they are white.
It is recommended that they be released at night in the tank, to give them an opportunity to find a place to hide while fish are asleep.

Anyone have recommendations on the best place to buy berghia for Aiptasia control? And how many should I get for a 29gal

_Alex_ · Sep 20, 2014

Best place I have found is

And for a 29 gal I'd say 3-5. Once the aptasia are gone tho they will die so will not continue to control them. With out aptasia they have no other food. If you only have a few than I would try another method.
