Two weeks ago I added 7 more to my group. I now have 13 C. delphax and the largest look splendid. The males have black extended dorsal fins. Very conspicuous. Right now, they are still housed with the , but I'd like to split them into a species tank to see if they'll breed.

Ten days later. Colors changing fast!

And the parents continue to pump out the eggs. Last night I collected about 100 and then this morning another 150 - all laid singly or in pairs within spawning mops. :-BD

Dang these Indonesian C127 are busy. After 250 eggs collected yesterday morning, I collected 253 this morning. Not all look good. I estimate 1/4 - 1/3 are unfertilized, maybe more. But that's still a lot of eggs!

The oldest fry are coming up on two months old. The parents continue to pump out eggs. I moved my into their tank in hopes that if spawning behavior is contageous, well, you get the point. ;-)

Offspring from Indonesian-sourced C127. Exactly 2 months old, 28mm SL. At this point they look essentially like small versions of the subadults on the day I bought them in May... Actually, that's no surprise because looking back on my records, their parents were only 30mm SL when I bought them! :))

FWIW, in the past I've described the dorsal and caudal fin stripes as "almost invisible" (on FB I think I called them "ghostly") because they seemed like remants of old faded stripes. I see now that the stripes are in fact brown, not black. On the young fry which have more of a transparent/ white/hyaline body color, these really stand out as brown, but in the adults with a tan/yellowish body, the stripes are closer in color to the body and look more indistinct.

Nearly 3 months. 30 mm SL. Haven't gotten much longer, but bulking up.

I've been keeping the in a 30gal breeder tank with my breeding group of Rineloricaria eigenmanni. This morning I discovered what looks like a Corydoras egg laying on the sand. I've transferred it to a net basket to see if it hatches.

If this is a cory egg, this would be my first spawning of Corydoras delphax. :YMPRAY:

Cheers, Eric

Correction: I sifted the sand and found a second egg! \:d/

Correction... 3 eggs! (Plus a wandering Rineloricaria eigenmanni egg kicked out by dad).
