Hello KilliorCory! I am from the Boston area of the US and really enjoying your videos of the corydoras that you keep in your fishroom. I am also a cory enthusiast and I have several common species like the Sterbais, Melinis, false Juliis, Similis. But I also have a big group of Green Lasers, Eques and most recently 9 Super Schwartzis. I am wondering if you were able to get the Super Schwartzis to spawn? I have been feeding them lots of pellets like shrimp pellets, Bug bites, and other good pellets as well as bloodworms and Repashy and keeping them in a 40 Gal Breeder tank along with my Eques . But they show no signs of wanting to spawn. Can you give me some tips if you had success with them? Thank you so very much and please keep your videos coming!

Hi Michael, thank you for the message. At some stage I really need to do a video on general cory breeding maintenance, conditioning and triggering methods I use. Basically you will more likely to get your corys to breeding condition if you switch to high protein foods for short periods; like freeze dried tubifex worms for week to 10 days. Then switch back to your normal feeding. And repeat with a few weeks intervals until you see breeding behaviour or females noticeably fill with eggs depending on the species. Then its all about triggering them to spawn. Conditioning first then triggering.

Hi there, i came across your video and heard you were asking for which species this is, Corydoras heteromorphus is a lineage 1 fish according to planetcatfish and a lineage 8 sub clade 4 fish according to corydoras world, meanwhile Corydoras cw015 is a lineage 9 species. So this leads me to belive that this is Corydoras cw015, looking at the headshape and snout. Kind regards Mike

That's exactly what I was thinking. Thank you for confirming. The head shape still looks unusual to me, interesting fish.

CW015 for sure

[@KillieOrCory]

Yes, since posting the video it became clear that they are CW015. Also managed to breed them which has been good.

Hello from Japan. Thanks for all your interesting videos on Aquarium. I've been trying breeding of corys for one year and a half, but none of them ever spawned. Anxway, would you tell me where I can buy the freeze dried blackworms for corys? Thanks a lot, Best regards, Kin'cory
