Boosting Results with Little Moss

Hey all. I have been reviewing this site for quite some time, trying to get the skinny on how best to care for and multiply CPD’s. I currently have 10 in a 20 long with 5 of the 10 (2 M 3 F) in a ~5 gallon area sectioned off for breeding. I have had a successful spawn, but it only resulted in 8 or 9 eggs, and all but 4 got fungus.
Here is the setup:
The breeding trap just got updated a bit to look like it does now. I ended up sticking the ends of the java moss through the plastic canvas to stick it in place. Hopefully it will start to grow better. In the meantime, would it be best to supplement w/ a spawning mop? Remove the trap completely and try only a spawning mop? Should the trap be fine as is, and it is some other factor? My water is very hard with a ph of 8. I don’t really want to try mixing ro if I don’t have to.
Another question, here is the hatchery:
It is filled with ~1 gallon of water and just has the air stone for circulation. How long can they stay in that without a filter? There are only going to be 4 for the time being. I will move them to a 10 for grow out, but I figured it would be easier to feed them in here for starters.
Any other advice?
CPD like hiding in alot of moss…
i start out with a small amount and purchase more…
I am not sure if little moss would make a different or not.
If I had enough moss, I would just forgo the breeding trap and leave the adults for 5-10 days in the same breeding area just full of moss, then remove them as seems to be the most promising option. Until then, I’m trying to do the best I can with what I have. I don’t really want to buy more moss, because I know that I will have an excess of it in a few months.
Anyone had success with spawning mops or a mixture of moss and spawning mops?
Hi there!
I had also just a little moss, so i made a big mop of black yarn and had the parents there for 5 days, then removed them. Worked just perfect (30 fry – previous post)Good luck!
Good to hear that the mop worked well. Looks like the total will be 5 fry from this spawn. 3 eggs have hatched with 2 more to go. I might just try the mop to boost the numbers a bit, but I will give the trap another couple days. I want enough fish that I feel comfortable putting some in an outdoor tub this summer and also fill up at least my 20 long.
Any thoughts on the hatchery without a sponge filter?

I have sponge filters in all my CPD breeder set-ups. When I move the fry on to grow-out tanks they have HMF’s.
I turn the flow down when the fry are small, (the first 2 or 3 weeks), but I can’t imagine keeping them in a tank without a filter.

How much of a bioload are new fry? With only 5 to 10 in there, would I be okay for the first couple weeks? They will be easier to feed and observe in the small tank.
I will move them when I know they are eating Walter worms (if my starter culture works) . Does that still seem too risky?

I try to feed my fry at least 3 or 4 times a day to promote good growth. I worry more about that than the bio-load of the fish themselves. If you feed live foods such as infusoria/green water it is much less of a problem.

Agreed, I start my fry in the 5.5 gallon breeder set-ups for that very reason. I must have missed something in the thread though as I don’t see where using a small tank precludes using a sponge filter.

It’s not how I would proceed, but there is more than one way to skin a cat. If there is one thing I’ve learned about this hobby, what works for one person doesn’t always work the same for someone else.
Best of luck with your new fry. Please keep us posted.

The water level in the tank is too low for me to use any of the sponge filters I currently have. I could fill it all the way and pop one in, I suppose. I have a green water culture that looks ready to start feeding them, and I also have some hikari first bites.
Thanks for all the advice, I’ll see what I can do about a filter.
