Finally! After three spawns from these Corys and not one hatching, I found just a few in the hatching tank; probably no more than half a dozen, but it's a start. During water changes yesterday morning I found a few youngsters in the adult's tank that look to be about 4 or 5 weeks old, so I must have missed a spawning at that time. Apologies for the bad picture, but the young catfish are very active and it's hard to find one sitting still long enough to get a shot.
Were there at least 10 fry surviving from this spawn after 30 days?
Thanks! Just read that nice write-up on the Brochis. Also perused those breeding reports. We shall see! Bartered off a bunch of fish to our LFS for a small Hydor 425 air circulator to create flow. One spawning report photographed a spawning mop, which we have yarn to make. Ground water from rain is high out here in western MD, and it comes in at 7.0 pH (compared to our 8.0 pH tap water).
I have an article in the forum section of this site as well. If I can find any of the pictures that originally went with it, I'll post them.
You can read about Brochis splendens here, including a link to 9 breeding reports: https://www.planetcatfish.com/common/species.php?species_id=114
The fish that are usually sold as Emerald Green Corydoras are actually Brochis splendens, which are a little more difficult, but definitely not out of the question. One really cool thing about these fish is the far different coloration of the fry- the young are really outstanding! Frequent water changes with cooler softer water, lots of live foods and some current in the tank should get them into condition.
Good luck!
Exciting! Question: we are setting up a Cory Breeding tank this week. What’s your top few recommendations for a successful spawning context? It’s a 20 gal long. Our fish are the Emerald green Cory’s. They’re reasonably mature. We have 4 Green and 4 albino. We’d love to get them to spawn...
While, Don, that's awesome! They are not an easy fish to breed. When I kept them, I would occasionally find young ones, but not many. I never saw eggs.
