I have had bronze and julii lay eggs so YMMV
for Pandas. You get about 6 and feed them catfish pellets and blood worms till they are fat. They will spawn. IME
a pair will so swimming together shimmying and dancing around looking for spawning sites. The first sign that I have noticed is eggs on plants and glass. If you see this then remove the others from the tank and when spawning is over remove the remaining 2. You really need a seperate tank for spawing and to raise the fry or they will eat the eggs. I have not tried to spawn them for fry rearing purposes though.
The female is the one laying the eggs
She is usually stouter.
