Is it hard to breed zebra danios?

How can i breed zebra danios?

• how can i get my zebra ddanios to breed? they are in a 18oltr tank with 2 black moors,2 orandas and 2 plecs.i have seen that many people sugguest marbles on the bottom of your tank but once they have hatched will the fry survive with all these other fish in the tank and if so what food should i add?

• Answer:

  You'd have to do it in a separate tank, that's the only way. The parents and other fish will eat the eggs, and any fry that does manage to survive. The marble method is how I've always read/heard as well. The idea is the eggs slip down between the marbles, so the parents can't get to them to eat them. Then when they're done spawning, remove the parents back to the main tank. A basic 10 gallon set up would work fine.
