20 g tank setup ..could you take a look? ETA: yay! frys!

Hi Jinx, welcome to the forum. There are probably as many people spawning CPD’s as there are different ways to spawn them. I can’t speak for everyone, but here’s what works for me…

I have two males and seven females. Should I move two females and one male?

I normally use 1 male with 3 or 4 females.

– is 20 g too big? Should I put a plastic canvas to make it smaller?

I think when in a small group, like a small breeding group, that they prefer a smaller tank. That”s one of the reasons I use 5.5 gallon tanks for breeder set-ups.

– does temperature mater? Do they breed in warmer water?

With my fish it does. They spawn the best between high 60’s and mid 70’s. When it get up to 80 they don’t spawn at all. I do have some young fish that AquaGirl sent me that will spawn at warmer temps.

– do they need added salt in the water? I have salt in the main aquarium.

I don’t add salt for any of my danios, they are freshwater fish.

– do i need to perform often water changes? I’ve been reading ppl doing breeding in a bucket..do you change the water There too?

I only leave my breeders set-up for 5 to 7 days, not long enough for me to worry about doing a water change.

My one male chases the other male..should I be concerned? I don’t see any courting behavior.

That’s pretty normal behavior. I’ve heard people say the males can be very aggressive to each other, but I’ve never experienced that. They spare around but no one gets hurt, no torn fins or anything like that.

Hope that helps. Maybe someone else will chime in with their experiences too?

I don’t use plastic canvas in my breeder set-ups so I can’t be of much help on this one…

Are they using it to separate the male from the females?

Would keeping them separate be of any use?

Well back in the day we used to separate the sexes to condition them, or fatten them up in preparation for spawning. Also with many egg scattering fish you want to be sure they didn’t just spawn yesterday.

CPD’s don’t spawn in typical danio fashion where eggs are scattered to and fro in one spawning event. Rather, they lay small clutches of eggs in moss or other vegetation. That said, I have never found it necessary to separate the sexes, but I can’t see where it wouldn’t do any harm either if that’s what you wanted to do.

I’ve never kept other fish in with breeders that I’m trying to spawn. I would find somewhere else for the guppy.

Several years ago, I kept a lot of dwarf shrimp. I never noticed the shrimp eating any CPD eggs, but the adult CPD’s where not so kind to the baby shrimp. :twisted:

Good luck & keep us posted.

Dennis

Congratulations Jiinx! Well done.

…do you need to have a filter necessarily?

Necessarily, probably not if you closely monitor your water quality. I don’t run any tanks without one though. I like to have a small sponge filter in the breeder tanks. Works as biological filter, very gentle water movement keeps the water surface film free, and it provides a multitude of micro-fauna for the fry to feed on too!
