They just look for the best hiding spot just like the cray, both are viewed as prey in their natural environment

I normally use 2 males & 4 females in 5 gallon set-ups. Lots of moss, room temperature around 70F-72F.
Remove the adults after 5 to 7 days. In 3 to 5 days you should start to see fry.
Best of luck with your breding project!

Yup, I used 2 males 4 females as well.
Update
from the top right wild female next highest f1 male just under a year male used for breeding (father) smaller wild male
4month old and 10 month old males (centre)

I know the pictures are blurry but I wanted to show one of the black one from my hatch next to it is a “normal” colour. The black ones seem weaker and get picked on when they are young. The heads seem a little more bulbous at this point anyway. There weren’t many to begin with maybe 10 -15 out 140 but now only 5 or 6 out of 80(the high mortality is due to the fact I planted my raising tank with plants that had damsel fly larva it has proven to to be a battle, I have started to disinfect my plants.
I thought I would update. This is a current shot of the darker fish
Very nice, they are a shy but curious fish I find, I really enjoy them.
I personally haven’t had any of my fry live with the parents, I have had some of the people I have sold my fish to have a couple survive to adulthood. I think it depends on their ability to hide and how many hungry mouths there are in the tank.@hdthan wrote:
I read somewhere that the capsules from bbs cysts can sometimes get lodged inside the digestive tract of fry, and small fish, killing them. If you’re feeding live bbs, and hatching them yourself, maybe this is something to consider. I’m not sure if you do, but just my two cents.
I have read about the casings as well.
A couple of questions
How long do leave your lights on?
How long has the tank been set up?
They are a very timid fish especially wild caught, it would actually concern me more if they were in the open under the filter rather than hiding, but still why is the question, maybe an o2 problem? Maybe shock? if you stopped fertilizing all at once I would just cut the ferts in half instead of completely stopping. I think any rapid change can adversely effect fish.Water quality as was said before would be ones first reaction, it is unusual and if the otto hadn’t died first I would say it were age. I have had them for almost 4 years and found them to be most resilient to bacteria and fungus even when other fish were infected in the same tank. They are sensitive to disturbance in their environment i.e sudden movement or light shock as well.

I’ve seen a number of juveniles that went from Yellow – to – Orange – to – Red, but they all end up Red in the end.

Agreed, I believe it just takes time. The females are ready to breed quickly, but just in reference to colour the females I raised are just starting to get their full colours after 10 months, compared to the breeders that is.
Hmm hard to say, less dominant males do not achieve the same colouration sometimes. I have a couple that are more difficult to id I think as they get older they are easier to id
Just for the record the “black” fish slowly lighten up they are still darker than some but after 10 months there is not a huge difference in colouration

OK, I have 14 Pearls – 10 from one source, 4 from another. The difference in colour between them is amazing. The 4 all look just like the photos on the forum home page, but some of the 10 are a little different – they are larger and have yellow instead of the red/orange. They all get fed the same and are in the same tank. Maybe I have some genetic mutation? Anyone else had something similar?
I had not noticed this reply you may already know but that is what the females look like. The ratio of male to female is good
