I really want to try out to breed these little guys what could I do to breed Zebra Danios quickily and successfull?

Amanda

They're egglayers, so the best substrate is 2 layers of marbles so that the parents can't reach the eggs & eat them. Other than that, they're breed by themselves if there is a large group.

Spawning net for any "egg robber"


This is the method I use for my danios.

How can I tell when they are male or female? I got one so far but I dont know If its male or female!

MPrudent

Easiest way to tell is by looking at their belly. The female will have a larger, more rounded belly. The male will have a very flat belly and it wont dip at all. Also the females seem to be more silver and the males more golden in color.

EvFreak

What do you mean by "dip"?

Nick G

Females are just fatter, bigger overall. If you go to the petstore and see a load together you should be able to see the difference.

EvFreak

Thanx Nick and everyone this is very good advice!

EvFreak

So lets say if I put alot of Danios together in one fishtank they will start to make babies without me doing nothing?!

Amanda

Unless you have somewhere to take the fry, I wouldn't breed.
But you need somewhere for the eggs to fall so that the parents don't eat them. The parents will also eat the fry, so they will need to be collected and put in a different tank.
