| || | I have posted ages ago. I'd say you sell the fry once they reach 2-3 cm in size. They tend to cost more as adults rather than as fry. The survival rate depends on how you maintain the tank and how you feed them.:)
If you can buy another tank, place two layers of marbles as substrate and make sure water is at half level. Then place a shoal of danios inside the tank. 6 is preferred. Males are generally slimmer. Females are plump and almost full of eggs. |
With water at half level, the eggs fall faster and slip between the marbles thus predation from adults is averted.
Adults will quickly eat the eggs as soon as they scatter them hence my advice for half-level of water.
Remove the adults after they are done with spawning. Then add Methylene Blue in the tank to protect the eggs from fungus. Aerate the water.
Prepare some brine shrimps or buy liquifry which is available in the lfs.
If not, prepare a hard-boiled egg, then scoop the egg yolk and suspend it in the water in a jar.
*Use this method only when fry is free-swimming.
The fry when hatched have yolk sacs and will stick to the area where they have hatched. They will be free-swimming after a few days in which time they'll search for food.
Provide some riccia fluitans(plants). they harbor microorganisms which serves as food for the fry.
