Breeding Corydoras caudimaculatus

The sterbai in the same tank were spawning often so I thought maybe if I gave it time the caudi's would sort them selves out but unfortunately never did.
Anyway recently I have been eager to see if I could get these guys spawning again but hopefully producing fertile eggs this time. So I set them up in another tank (where they are the only corys). Within 5 days they started spawning but only a few eggs here and there. A couple weeks on a total of 30 eggs with only one being fertile, which hatched this morning. They spawned again late yesterday afternoon after having a water change earlier in the day, collecting a total of 19 eggs last night. On closer inspection this morning there are 3 fertile eggs so it seems things are starting to sort them selves out, so hopefully the number of fertile eggs continue to rise.
After observing them spawn again this time round it appears the bigger of the 2 females still seems to be a little clumsy with cupping her fins so she keeps dropping the eggs. Anyone else observed this with a female cory?

Always the way eh.
Temp has been 25-26.C
These guys have been spawning regularly since shortly after the move to their new tank. But unfortunately the fertility rate is still very low, collecting 45eggs yesterday with only 8 being fertile.
Not sure if there is anything I can do to improve fertility?
Good luck with your guys hopefully you can get them spawning soon.

How many males do you have? the more the better with all cory. My albino's spawned a mouth or two ago they were only about 1/2 growen at the time lost all but 2 my fault they were quite strong but the tank went off.

Well done with the C. caudimaculatus, mine are also spawning right now, they are into their third session with a 4 - 5 week gap between each. There are 4 males and 3 females in my group, but it is only the one female that' doing the producing, so far she has laid batches of 25 - 22 and the last was a fantastic 68 All in all the fertility rate is around 80%, which pleases me because they are a species not renown for their fertility. I also concider this species to be somewhat seasonal.

I'm hoping the fertility rate will improve with these guys, its has been quite low so far, 80% would be great.

Can only hope getting more caudi's out in the market it will sort out these mislabeled similis, although I can see it wont be easy.
I went into a lfs recently that had similis mislabeled so I informed them they were infact similis and not caudimaculatus but they said "they were sold to us as caudimaculatus".
Be interesting to see what they would do if they were sold some 'similis', surely they couldn't sell the one species under 2 different species names??
