Did My Fish Just Have Babies?

[nosoup4you]

Danios are egg layers so they do not get pregnant they become gravid. Here is a pic of a gravid female Danio:

Congrats on the fry! Updates as they grow would be great.

Danios are egg scatterers. They swim quickly up and down the length of a tank and scatter eggs along the way. The males will be chasing the females and dropping sperm. Eggs that manage to fall into places like between pieces of gravel will not be found right away and eaten. Those eggs will be the ones that hatch and provide those extremely small fry that you are finding.

O,ok, so really there would be no use putting a female Danio into a breeder since they need room to swim and drop their eggs. So the only way to keep the fry safe in this case is to wait until I can see them and then put them into a breeding net right?

Also, should I not vacuum the gravel for awhile in fears of sucking up some of the egss or doesn't that matter? would those eggs maybe not be fertile?

A commercial breeder of them would have a shallow tank with a very course substrate, like kids toy glass marbles. The shallow water means the eggs quickly reach the bottom and the large substrate means lots of places for the eggs to fall. They will put conditioned males and females into the tank and let the breeding go on until it stops or slows a lot. At that point the adult fish come out of the tank and the eggs are left to develop and the fry are fed once they hatch out. You will normally not see many, if any, fry in a community tank because of the predation that happens in that environment. I have seen my zebras breed many times but have never found fry because I have a relatively fine substrate that provides few hiding place and I have a lot of different fish that all like sushi.

unless you set up a spawning tank then you can add a male and some females ( nice fat lumpy ones) let them do their thing , remove them after 2-3 days and then wait and watch for baies
thats what i do with my minnow
