berghia nudibranch Eggs experience

[sixty_reefer]

Was feeling a bit bored so tough I’d start scrapping some nems of the weir to make feeding later more easily.

I’ve turn to research the past few days, apparently there’s no way to breed Aiptasia in a closed system by spawning, Only by laceration, this is wend the anemone moves and leaves behind part of its foot. I’m now really intrigued on the why and I want to experiment with it I believe I may have stumbled in a way to get them to grow in large numbers, Hopefully if it works ( trying to recreate what I did the first time) this information could benefit the industry and breed this animal in a large scale.

What is the overall update on the Eggs? Have they hatched, or whatever berghia eggs do?

Can’t tell to be honest, the cord we’re the eggs were is empty, but can’t see any nudibranchs walking around just yet. I did put down a small aip in the container to encourage the nudis to hatch, she’s always closed but not gone yet. Just wondering if they too small for me to see, am going to give it another week before I consider it a failure :rolleyes:

I got one of these for kids, and it's quite amazing to look at things close up.
Way better than the Cheap Toy Optical Microscope we have.
Has a light too.

I used it once to look at copepods.
You will be able to see if the Eggs are alive and moving.

Amazon product

Cheap (about the price of One Adult Berghia)
and fun to look at all kind of things close up. Still and Full motion.

This the example.

Some Macro Algae from my Algae Scrubber (WITH Camera)

With Scope.

This is a bit of zoom.

More Maginification.

Full Magnification.

Wow that's some really clear images, I think i’ll order one of those just to see what’s around

If you get one....Don't do a zoom in under your finger nails.
I showed my kids, and they scrubbed their hands like never before.
:) LOL :)

I bought 4 berghia years ago and literally raised them in a plastic coffee can with an air stone—no heater or anything. I fed them aiptasia and they multiplied until there was about 30 of them and I released them into my tank. IMO they’re easy to breed/raise and the limiting factor is the aiptasia supply.

am starting with eggs as i tough it could be cheaper, it’s been 2 weeks now with no sight of baby’s so far, I may have to go and buy a few adults soon. Am currently trying to work on the aptasia side, as you mentioned they are the limiting factor for berguia breeders if we could work out how to make the larvae grow in to adults this could be beneficial for the hobby as an adult female could spawn up to 10.000 eggs per event.

This is my first baby from a egg, it’s only a couple days old and about one millimetre in size, my goal is to see if they can survive longer than 6 weeks in aquaria.

That's kind of funny.

You went from Trying to raise Berghia's to eraddicate Aptasia to breeding Aptasia.

That's a pretty good close up photo of the Aptasia.

I put 4 medium sized in my 30 gallon sump a few weeks ago and its kinda hard to find an aiptasia now. 2 of the 4 was already stuck together and most likely breeding/ laying eggs when I got them which was probably helpful.

I thought the eggs had to b fertilizer by the bigger berghias. Thought I read that some where

I have raised berghia before started with 5 ended up with over 200 couldn't keep up with them just started breeding since again had 8 now at probably over 20

Being able to keep nudibranch alive long term always been something I wanted to do, I think that wend I got the eggs it just clicked again. So my goal has changed like you said from completely eradicate aptasia to try and be able to keep enough aptasia in the sump area to keep this guys going. There’s a guy on here that done quite a lot of scientific work on this, let me tag him and see if he can bring some input to the thread.

Am not familiar on how the berguia breed yet, I’ve been more focused on the food side of things. How many nudis did you get per cord of eggs? And do you remember how long till they visible? I’ve got the container in sump for 2/3 weeks but can’t see anything yet.

I get alot of my information from salty under ground she has a good write up on them it's a website but found a nice article on wikipedia's I believe too

 

[Grallster]

IME, there’s always a scrap of aiptasia left somewhere that starts to grow back after the berghias in the tank starve to death. It’s super important to remove/nuke them before they start multiplying.

I think ive read most information in the web including the article from advaceaquarist.com, you would be able to share the link from salty please?

Your probably right, I’ve never used it before to try and eradicate Aiptasias. my goal has changed since the start of the thread from eradicating Aiptasia to keep this guys as permanent pets I’ve also found a frag with some bryopsis so will cultivate some to add a few lettuce slugs to the tank we’re I intend to keep Just nudibranchs.

 

[sixty_reefer]

I got tired of waiting for the eggs to hatch and got a couple of adults today to keep me motivated.

Sweet! Those look like nice big ones!
