The water I used was from the "Kaimai Spring", heated to approx 26oC, and a touch of meth blue or similar to try and control the enevitable fungus.
Also a handful of java moss to promote infusoria.
I use a small "U" shaped sponge filter for circulation.
And I also have a long pipette that I use for sucking off any eggs that I see aren't fertile or are fungusing.
They develop a white spot in the egg which continues to consume the egg to bursting point, then of course that contaminates more.
So get them out early.
Just before hatch time, the fertile eggs get very loose and with only the slightest provocation will fall off.
These are picked up and are placed away from the hatching area, but still in the same tank.
The eggs hatch and literally just sit there slowly changing to the wriggler stage, then to the "jumpers", then free swimming.
My babies took BBS straightaway and also micro worms.
A couple of ramshorn snails are added to control any left over BBS, and as general cleaners.
Water change three days apart with the same type of water and temperature.
To give you an idea of the numbers, I had about 100 eggs, about 30% fungused, and another 50% odd of the babies that hatched did not survive up to a week after free swimming.
Now when I go out to the shed, they are out to the front begging.
At the moment, I have an excellent A. melgar with a nice little batch of almost, free swimmers.
My teenage A. eronotus are showing signs of spawning, ie. colouring up and guarding a pot.
So hopefully, I'll have three species spawning soon.
