Did you have any luck?
I breed CPD as well, but I've never had any luck moving the parents back and forth. I have a 20g long with about 12 adults, a thin gravel substrate some driftwood and a big ball of java moss. I also have a bare bottom 5.5 gallon with a sponge filter and another big ball of java moss. The only way I've gotten fry so far is by swapping the moss between tanks, and waiting about 3-5 days before fry appear.
I feed my adults Micro, Walter and Bannana worms and they like all 3, I'll also occasionally give them frozen blood worms. There main diet is golden orbs which they seem to really like. I tried the micro pellets but I thought they were to big for CPD.
Anyways, let me not if you got any fry and how you did it!
I'm actually going to be moving the fish out of the tank today so ill see if they spawned or not if any fry appear.
Problem is my fish barely eat the food I feed! I want to try banna worms but the cultures on aquabid are expensive,well nit expensive but you know what I mean , where did you get yours and if you don't mind me asking how much did you pay?
I'm hoping if they did breed that they didn't eat any fry because they just don't really eat any food I give them.
But I will order the golden pearls food to see if I have any luck.
How long did you typically leave the parents in for?
