I have 3 albino corys and occasionally find eggs in my tank. I assume it's the cory's laying the eggs, but they always get eaten within about 24 hours. I've never known how to sex them, but if the females are larger, then I think I have 2 females and 1 male. So if I want the eggs to hatch, I need to move them to another tank, but how do you collect them? They are scattered around the tank, on leaves, on the glass and sometimes on the substrate. Do you have substrate in the tank you move them to? And do you just drop the eggs in and let them lie where they fall? How long until they hatch? So many questions.

I personally would seed a sponge filter in my sump or you could purchase a Marina Breeding Box I got 3 from Amazon. The seeded sponge could go in a 10 gal. just remove the leaf and place in the 10 gal. Also connect a air stone this will keep the water from being stagnant so eggs won't get fungus. Also adding Methylen Blue will prevent fungus. Make sure you seed the sponge for about 2-3 weeks before trying to hatch eggs. Also be prepared to have fry food for them when they become free swimming and absorb their egg sac. GL.

If you use the Marina Breeding Box all you would need is a. Air Pump rated for 10 gal. connect let fill with water from the main aquarium drop leaves with eggs on them and continue to do water changes as usual to me this is the easiest option.
A breeder box will work only for the first 2-3 weeks as long s there aren't many baby corys i it. I would still "water change" the breeder box daily with tank water by flushing some water out, and keep it clean from food left overs.
Then they need a cycled tank. Mine would grow to 2-2.5cm in 2 months and space soon becomes a problem.
As for hybrid corys, I was misfortunate to raise some myself. I kept albino aeneus and gold laser groups in one tank. Both had males and females in the group, 13 vs 6 corys. I've seen them with my own eyes interbreed and I still have their hybrids offspring which are about 5-6 years old now, although I killed a lot of them when my last tank gushed out on the floor.
Despite how they are labelled on some websites, gold laser corys and aeneus corys are not related species at all. I had that confirmed at the time by prominent cory keepers and so far mine is the only record of these two interbreeding, as far as I know because I haven't checked recently. I have recorded all action, even have some videos The offspring is beautiful though, larger and healthier than their parents on both sides. The offspring is also fertile and produced eggs, though I didn't dare raise any, yet...

why are you hesitant to raise/breed the hybrids?A breeder box will work only for the first 2-3 weeks as long s there aren't many baby corys i it. I would still "water change" the breeder box daily with tank water by flushing some water out, and keep it clean from food left overs.

I already raised the first generation. As for the second, I haven't really had the chance as I went through some tank break ups, things dragged out, etc...and now the remainder are in a community pond, no eggs will survive unless I see and collect them. But it will be interesting.
You may notice in the commercial breeder contraption in my photo, it is submerged in the tank, this constantly changes the water in the box, but I found I needed to squeeze out the filter the filter pad daily (sometimes twice daily to maintain water quality, and keep eggs viable.
