Thanks Adrian that's the one.Very similar results to what I am getting compared to your March 1994 data.Do you remember roughly what your Male to Female ratio was with the fry raising?.

No Mark, I don't think that I recorded the male/female ratio. However, I think I would have recorded any skewed ratio if it occurred as I usually did as a general rule? Adrian |

I can't wait to get a colony outside this year.Adrian.when do you think is best giving east coast USA months and temps to move some outside.I am thinking late May and running right through September?.Then I can log comparative data from tank breeding and raised inside.just got some eggs going so. should have plenty ready to go by then.My latest little colony is fired up and throwing plenty of eggs already.

Caught some nice footage of males sparring. Hopefully they settle down again and get back to business!

I don't know the temperatures of the east coast of the US. However, these are some temperatures from their natural habitats in Queensland:
14 – 26°C
18 – 23°C
13 – 28°C
18 – 33°C
13 – 27°C
These temperatures were taken over time (months to years) and gives you a better picture of what their natural conditions are. I know that they have been kept at lower temperatures in captivity, but their survival is at risk if you go down that path. The big problem with outdoor ponds is if you get a sudden drop in temperature and the water takes too long to get back up again, you can lose the whole population. I have seen this happen here in Queensland a number of times. That's fine here, as one can just go out and collect some more, but in your case they would be hard to find, so just be careful when you choose to breed them outdoors. You can actually get more numbers if you breed them indoors. I think outdoor ponds is just the lazy fishkeepers guide to breeding fishes. 
A well-designed permanent decorative pond is different than a breeding pond!

thanks Adrian. I will definitely wait till it warms up at least water temperature in the 70s . i'm really interested to see how they do on a more natural diet. not worried about losing any although I definitely don't want to lose even one .I have about 4 colonies in different tanks and a bunch coming up plus eggs. so no real danger of losing these. I want to try to simulate what Leo did and basically compare results from what I'm doing inside. I have to figure the food source is going to be much better outside coming from nature rather then processed frozen and the typical common tank raised cultures. I'm really curious as to why certain species lose that dorsal extension after time

Have a look at this outdoor pond setup Mark :-)

Thanks Adrian :-)
I have seen pics of this set up while it was in the construction phase. There were discussions about the cost of running all that, especially in the winter. It's personal choice on how you want to set up your outdoor ponds. Looks cool, something to show off, but the functionality of breeding multiple bow species is pretty low.
My worry with this set up is, rainbows are jumpers. I can see them mixing themselves up with those ponds being so close together and the water levels being so high. Similar to what has happened with the FFF in the past. I've seen rainbows jump out of containers as high as 18 inches above the water level.
I remember when Lucas was setting this up, we advised to at least design lids or covers of some sort to prevent hybrids. Also to help lower the heating costs in the winter.
Lucas, are you on here? How is your electric bill? How has the weather been? Any large amounts of snow or cold rainfall? How did that affect your water temps? And do you have anything in place to avoid the ponds overflowing?

Another little experiment I wanted to try was separating the light/dark fry I see hatching out. Often wondered if this is an early sex determination sign or something else. I did leave a few in the container for a couple days to see if they would change.But they stayed the same. Could be interesting. Counting light/dark as they hatch. Will see later if this tells me anything.So far it is 8-5 dark.

That could be an interesting result?

Yes, I noticed it with my fry and wondered about that. I hope you'll find the reason.

We will see guys. could be nothing but ,I imagine it shows for some reason or another.
12-8 dark..still more to hatch.I will already say the dark may be males..just an early guess.. I will stop soon then let them grow out.. but I love to just keep collecting! lol..I am thinking later to photo the tank to see how close the counts is.
Note* I really don't see this is Melanotaenia, Glossolepis or Chilatherina species...Anyone else do?.seems to be more blue-eye specific ATM.Will have to pay more close attention to others now.
