For those that are interested in the future of our hobby, this is very exiting news - 70+ days is a long time until settlement which is why it is so difficult to raise this type of fish.

When do they paint them yellow?

They place them in a bath of fluro Mountain Dew.....

Oh, and thats a awesome pic in the O.P....

I a pretty sure all marine fish 'settle out', or go through a metamorphosis where they change from a larval fish to a juvenile. It is at that time when they take on their normal colouration.

I thought they fed them lolly bananas!

This is huge news! I've been following it as well and it's amazing to see how far they're starting to get them along now :)

My personal favourite is Bali Aquarich, the work and sheer variety of species (mainly angelfish) they have breeding and being aquacultured is just amazing! I would just love to get an aquacultured angel from them, especially the bandit's they're working on ;)

They don't say whether these larvae are TB or WC eggs which is either here nor there in the grand scheme of things because we're learning about their larval stages. My guess is these are WC eggs that they'll raise and use for broodstock like Bali Aquarich has for their stock. It's an exciting time we live in today, I never thought that I'd live to see so many new advancements this quickly in the hobby. I knew we'd unlock the secrets, I just didn't think it would be this fast.

@ReeferRob an educated guess would be that they are working with WC eggs.

I'm 99% positive of that too MagicJ, but these specimens will know nothing but captive life so we're on our way with these as well.

I read an article from James Cook university and there is a guy there breeding cleaner shrimp, blood shrimp and even harlequin crabs!!!!!! The future is looking exciting, I would love to get into this line of research

Cleaner shrimp and blood shrimp are tough, peppermint are a lot easier. Justin Credible uses their eggs and larvae to feed Goniopora corals.

With 180+ day settlement periods tough is an understatement ;)

ReeferRob · Oct 13, 2015

Yep, it's 63 days to settle for my Bettas. :( Then they turn into flaming jerks. :mad:

Is settlement the period of time before the eggs hatch?? I have no idea about any of this, but am extremely interested in it

ReeferRob · Oct 14, 2015

After the eggs hatch. After they hatch, they become plankton for that period of time.

As Rob mentioned, marine fish, shrimps etc hatch into a larval form - they float around in the plankton for a period of time before going through a metamorphosis and settling out to the 'finished product'.

Some fish have a relatively short settlement time i.e. my Amphiprion ocellaris started settling out at 9 days post hatch - these yellow tangs are at 70 days and are not yet settled out - red line cleaner shrimp can take over 180 days to settle out.

The difficulty arises because you need to be able to feed the correct foods in the time before settlement - the longer this period the more likely they are to starve to death.

Oh ok, thank you for clearing that up. I saw another post today about the yellow tangs from hawaii and they have over 1000!!! at the 36 day mark. They also mentioned in their blog post that they are beginning to feed a wide variety of foods all the time and even showed some footage of the 49 and 36 day old tanks.

Hopefully this works https://www.facebook.com/Rising-Tide-Conservation-850675348332972/
So the video is just on their page, here is the link to their blog posts http://risingtideconservation.blogspot.com.au/ . I will be keeping an eye on this cause they are also captive breeding melanunus wrasses

If not just search Rising Tide Conservation into facebook and it will be on their page
