Hatching Enviroment For Cory Eggs

[Xebadir]

Having read many varying opinions on the successful hatching of cory eggs id like to start a discussion on what you, the learned community of cory keepers on TFF feel about the ideal conditions for hatching corydoras eggs.

My opinion is: Nature is prone to take its course, so hence i do not believe in meth blue and have lost very few eggs to fungus. I believe in keeping them under light, with aeration from airstones, using water from the tank they were laid in, note that i dont believe in heating the tank either(all my cory tanks are unheated).

What are your thoughts out there?

Should be interesting, Xebadir

When I bred the bronze Corie's, I'd roll the eggs off the community tank wall and roll them onto the glass in fry tank. We did use meth blue once, but the fry seemed to have problems and mostly died. Thereafter, no meth and we only lost a few to fungus. I had an air stone to start with then moved on to sponge filter.

But when the pandas started spawning, I tweezed the piece of java moss off the log with the egg on, not touching it at all. I then placed them in the breeding net in the fry tank and once the fry hatch, they stay in there till they're about 10-14 days old. They're then released into the fry tank, where I grow them out for sale. I have two sponge filters pointed at the net, so there is a constant flow. I have some sort of snail in there, that keeps all the muck out and if there are eggs with fungus, they seem to eat the fungus, not the egg. I'm now using this method to hatch Trilineatus eggs, my second batch. Unfortunately I lost the first spawn, the parents are still very young. Not sure if this has something to do with the quality of the fry.
