Hi, I will be getting a shipment of these guys next week, and would like to breed them in a display tank, since I don’t have a place for a separate fry tank. If/when I move to a bigger place, I will set one up, but for now, I just want to have some degree of success in the adult tank. I am aware that the adults are quite voracious fry/egg eaters, but just humor me and give me some advice anyway.
The setup:
Tank: 20g Long
Filter: Eheim 2215
Substrate: Eco-complete and sand
Lighting: 2x55W Coralife fixture run on a noon burstPlants:
HC
Dwarf Hair Grass
Stargrass
Hygrophila ‘Porto Velho’
Hygrophila Polysperma
Java Fern ‘Phillipine’
Fissidens Fontanus
Taiwan Moss
Blyxa JaponicaIntended stocking:
20 CPD
10 Pygmy Cories
RCSAs you can see, the tank is fairly heavily planted. However, there is also a good amount of open space. I hope that the CPD will not be shy and swim in this space. I also hope that there is enough cover for for the fry.
My questions:
Do CPD school?
Are they more likely to breed in a large group?
Where do they spawn and drop eggs? (In plants, on bare substrate, is there a nest, etc)
Does keeping the adults well fed help at all?@fishscale wrote:

They will tend to move in smaller groups & in a heavily planted tank will hide under cover most of the time but they do come out if patient and the groups will merge together.

They will breed in small groups and in a larger tank with many spawning sites small groups can claim these as territories.

The male (or males) will drive the female through the plants when mating – your blyxa will be a good spot (as is mine)

definitely, & I got better spawnings when feeding live whiteworm twice a week, which was my live food of choice.
By keeping them in a tank like this you will get fry but not as many as putting them into a purpose breeding tank and then removing them. I also do it this way though and I vac the main spawning areas & get newly hatched fry & eggs which are then deposited into grow out tanks with the water from the planted tank. I also keep my eyes open for free swmmiers and rescue them ASAP as they will get eaten.

What do you use to move them? Turkey baster?
No I just use a plastic jug but you could use that
It’s a species only tank although mine has shrimp as a cleaning crew. The tank is a 180litre (about 47 USG) and houses around 30 CPDs.
I’ve currently been rescaping mine so the fish haven’t bred for a while but I can see they’re settling down now.
At their height I was getting 20-30 fry a week that were removed at water change time each week and put into a separate fry tank.
