I picked up 8 CPD's today from That Fish Place in Lancaster. Anyway, I'm kind of confused with breeding.

It's a 10g tank, and I have 2 baseball-sized hunks of java moss on either size of the tank. I can add more, I have about twice that much in my basement too. It's pretty heavily planted on the sides and back, but there's a small open area in the front-center.
Sorry the picture is terrible, it was taken on my phone (can't find my camera.)

I was told by the guy who was helping me out (who I had an hour-long tour/conversation with, and was the first pet store employee I've met that knows more than me about fish) that let them grow a little more, and they'll end up doubling their population every few months, and that I should keep the numbers around 15, moving or selling fry if it gets above that.

Is this valid? I've heard different suggestions, some say they eat fry madly, some say that their mouths are too small to eat them. What I was planning on doing was something like this:

Pretty self-explanatory, I may do a small, unheated spawning tank with rain-like water. I would wait until it's a little warmer in the year, so that the room temp would be 73ish.

I had also heard about/planned an egg collector for in the tank like so:

Which way (not necessarily the ones above) would you reccomend?

Any tips?


Thanks :)

If you plan to use an egg trap I would put it in the center and use the bowl method so its easy to pull out and check/remove eggs. However with that I"d take the moss and any other ground cover type plants out so that they focus on that trap in the center.

I've read of them eating fry, and I could totally imagine that as newborn fry are tiny, but if your tank is heavily planted, say java moss completely covering the bottom, I'm sure many fry would survive. I've had good luck in heavily planted tanks but I'm sure the fry survival rate would be much higher if the parents were removed.

Good idea. I took out like half the moss in there this morning so I could actually see them when I got home.

That makes a lot of sense. I might use the trap periods of time when I have a grow out tank available, and when I don't, I'll let nature take it's course.


I'm sooo excited about these guys. This is the tank in my room, and they're a lot more interesting to look at than shrimp (which got eaten by dragon fly larvae:swear:). These are actually more spunky than I anticipated, they are a little hide-y, but they're swimming in open areas where I can see them :)
 
mine liked to do it under an arched driftwood, and they breed more using natural sun light so the real dusk and dawn i think is key i had more spawns with that tank than with the other,.

man really can't mimick real dawn,.. my tank had just enough light to beam in there morning and night but wasn't there in the main hours,..lol worked great, i think this is why they breed good outside,.. the lighting....jmo;)
 
I can't help ya with breeding them,but I really like your jungle :)
 
For sure they eat their eggs, and probably very small fry, too. If you had a second planted tank, you could just switch them back and forth after spawns so that they would constantly be breeding, not eating the eggs, and the fry would be big enough to be inedible by the time they were put back. Of course, that'd mean another tank ;)
