How I'm going to try to breed CPD's.

[Piranha86]

What I'm planning on doing is raising/conditioning a shoal of 8-10 in my 10g, and then selecting pairs/trios to put in a 2.5 with a lot of Java Moss to spawn in. After they spawn, I'll take them out and raise the fry. After the fry are in grow-out, I'll put a pair in there again and repeat the process. Does this sound OK?

It sounds good. I've attempted this myself, but it seems like I get a bunch of fungus on any uneaten food and unfertilized eggs that are down in the grass. I now have a method to catch the eggs, and I'm trying it out right now. It has worked in the past with other danio species, so I hope it will work with them also.

I got the idea from the best danio person I know, a man named Dennis. (danionins.com)

Mademan has great success keeping shrimp (he says ghost shrimp but I think they're wild cherries) in with his killi eggs/java moss. He says they keep the eggs free of fungus.

I was planning on just using Methellyne(sp?) blue or something of that nature.

Jetajockey, how do you catch them?

I went that route the first few times I tried it also, it definitely helps, but I figured it was easier to have something to collect the eggs, that way the fish never have to leave their tank.

I was having issues with them just getting comfortable, they seem to be a rather timid fish at times, and they only breed for me when they are settled in.

I used a 5g and put 2m/3f for 5 days, covered the bottom with both marbles and java moss, pulled them out. Tried this twice and didn't have any eggs at all. Then I did it again, but instead covered the glass on the tank with newspaper on all sides, and this seemed to work because I had eggs (fungused, but still).

Jetajockey, how do you catch them?

In that picture above, it's a pyrex dish with a lid, I cut a hole in the lid, as big as possible with the lid still able to fit over the top of the dish. Then I glued some plastic mesh canvas over the hole, and tied some java moss to the center of it, to give them an area to spawn in. The eggs get scattered over the java moss and fall down in the holes of the mesh and into the container.

This method works well, although danio eggs are so tiny that it is very hard to see them. I can't see them without pulling the container out of the tank and looking through it with a flashlight.

Great! Thanks!

And also, the main tank's going to be heavily planted, so I may get a few that evade their parents to grow up in there.

Jetajockey, would this work? It's a much smaller bowl, with no lid, but goes by the same idea.


I think I'm going to get a shrimp colony going, and then add CPD's.
