Day 1 The Egg Collection 

24 hours later. Approximately 200 - 400 eggs. 
About 1/3 are clear and empty. The rest are translucent brownish coloured.

They are in a clean 2.5 gallon tank.  1 drop Methylene Blue, Airstone and RO water. 
I’ve noticed a couple of Planaria amongst the eggs. I will try and get them out but nearly impossible.

400 + eggs on closer look.

Eggs are starting to clump together. 
@WhitecloudDynasty does this still look good?

They aren’t moving around in the flow. Just settled in that one area.....?

I’ll have another 150-200 eggs tomorrow morning for a second 2.5 gallon tank with airstone too.

Looks fine...sometime all of mine look all fungal up but still all hatch

Well they are definitely all fungusy.
But are beginning to hatch in the past few hours.

A couple dozen so far. 
I am keeping them in the dark wrapped in black cloth. 
Air stone on low. 
I am slowly removing water and adding RO water to remove Methylene Blue. 
 

2nd batch of eggs is one day behind and not clumped together...yet.

@JoefishGofishfollowing intently and wishing you luck! Thanks for documenting your process, as well as failures/successes so completely. I really enjoy these beautiful native fish and hope to have the chance to keep and breed them one day, so please keep documenting your results! I'm hoping that some day I will make good use of them. And in the meantime, I can at least live a bit vicariously!

Thanks for the good wishes. This is at least attempt #7 with successful egg collection and I continue to hope for the best. 
But with only 2 living fry from batches earlier on I try not to get emotionally invested. Just excited each time there are eggs to coax along. 
This is a window into the notes I’ve kept in terms of spawning cycles 

I got better at creating places for the fish to spawn and easier to collect the eggs  

November 29-spawn-no collection 

December 21 - spawn + 30 eggs

January 3 - spawn + no collection

January 17 - spawn - 100 eggs

February 1 - spawn - 40 eggs

                 3 - 50 eggs  

February 6 - 20+ eggs w/tails in tumbler

February 17 - spawn

March 5 - spawn - no eggs deposited in containers 

March 19 - spawn - no eggs deposited in containers

April 6-7 spawn - collection 48 hrs later

  • lots of detritus
  • Approx 200 eggs
  • 1 drop Meth Blue
  • About 100- 150 swimming April 10

(Present) April 20-21 spawn 400 + eggs. 

2 spawning days each 400 + eggs

My measurement (1 drop) of Methylene was crude at best. I dipped a chopstick in the Meth and dripped it into the first tank.  Fearful of adding too much I removed about half of it (the dye is so easily traceable as it descends into the water..)

The second harvest of eggs received closer to a full drop or more. The results speak for themselves. 
Tank #1 the eggs grew fungus quickly and balled up. There are at least 100 fry hatched as of this morning

Tank #2 which had more Meth added and is more Blue in colour.

Eggs are spread out and lying flat on the bottom. They should start hatching today.  Very curious to count and compare. 
 

I’ve done partial water changes on both.

Tank #1.  Approx 100-150 fry?

Tank #2. Approx 200-300 fry?

(can’t seem to orient pic right side up)

@WhitecloudDynasty your tips so far have proven my best hatch rate yet. 
I still feel like I’m going to crash and burn.   But there is really nothing to do for these guys until they are free swimming and able to take food. 
Another 5 days or so....

So Day #7

Tank #1 I would guess 50-75 fry remain. 
4A0B6504-9808-4086-976E-D3D8CFD6AEDC.jpeg.9c36e88703f3c32b45ed9d8116ce88f8.jpeg

Tank #2   I’m guessing 100-125 fry remain.   So hard to count. 
They have eyes and some fish body structure to them.   Swimming is kinda like darting around and then falling to the bottom.

The next thing is to move them out to a bigger tank with actual filtration and plants and leave them for a year or so until I can put them outdoors in my summer pond?

Or leave them a week or so longer and start water changes?  The water has been a touch cloudy today....?

They would go into a heavily planted 75G with some Black Neocardina shrimp and 5 Blue Neon Loaches.  I just moved the Gold White Clouds out to the pond for the summer

I would lose track of them in here but imagine it to be a great environment to grow up in....?

Any thoughts or suggestions would be helpful  

There may be early spawning activity ramping up with the adults. Subtle colour changes and increased activity. My basement is warmer by several degrees and the tanks are up to 69FC298D1CC-C72E-4454-A1BC-4CC89AF3823D.jpeg.8f302f27611e1638689aa8d1dfb5d926.jpeg
