Hi, can you tell me any info on them, are they hard to breed , hard to keep, one of your favorites ? Is 6 enough for a breeding group ? Happy Thanksgiving to all!!!

If you look at , you'll find most of the information you need.

The "normal formula" for cory breeding, I take it, is 2M/1F, plenty of meaty food and a cool water change.

I have a group of pepper cories, and they have spawned 3 times now already.

I can't call myself an expert - but can tell you what I did.

I kept them in a 2 ft tank (they are busy enjoying their 3 ft now) with gravel that looks like course salt.

I did a 10% water change every 2 or 3 days (you can do 20% per week if you like). I feed mine tetra prima granules - which they absolutely love to eat.

Take good care of them and they will spawn over and over
again.

Pepper's are the easiest cories to spawn (so I hear) and it really isn't hard to look after them.

C. schwartzi are easy to keep hardy fish but not easy to convince to spawn. I had mine for years and they never did anything. I then added some C. panda who did start spawning almost immediately and then pretty soon the C. schwartzi joined in as well. I have read other stories about them needing to be triggered by the hormones released by other spawning corys.

Generally, peppered corys are , which is indeed one of those that are easy to breed and keep. C. schwartzi[/clog] is probably one or two steps up on the difficulty scale, but not "near impossible".

Hi,
If you don't mind my asking , where on earth did you find tr C.shwartzi? These ae hard to breed Corys. Sterbai are much easier, especially tr fish. Since my breeders began their season I am now up to 1000 fry and more every day. This will go on until the season winds down in March. All advice and info on stickys will help you breed C. sterbai but shwartzi is still among the few that remain very difficult to induce spawning. I happen to like them but sterbai have much more color.
Also if Corydoras sterbai cost twice as much as "tank raised" C. schwartzi, I smell misrepresentation. A tank raised Cory. schwartzi would be worth as much or more than tr C. sterbai.

Hi all, Larry I found them on aqua bid , the seller is mostly on the plant section but his web site also has cories. He has great feedback for all his items.. Betterbettas has Wild sterbais, all there fish are wild, they say wild are more colorfull than the imports etc. I think Ill buy the sterbai, now breeding wild fish, I dont know, real hard but I like them alot, which is the most important thing to me.

H vinnie and flash,
I have a theory, fwiw, if you get about six wild sterbai and can mix them with a breeding trio of tr sterbai you just might be able to get the wild ones going.
flash,
You demonstrate my point, I remain suspicious of anyone selling purported tank raised C. schwartzi but I think you have a better chance than most. Having a large group in such good condition is a good start. Knowing that you have spawning Corydoras trilineatus on hand, I'd be tempted to make a water change and take the water from the spawning trilineatus and putting it in with your schwartzi. Maybe do the coldwater water change trick first before adding the pheromone containing water. I suggest removing any carbon if there is any in the schwartzi's filter system.
This has worked for others and maybe it will help you break the ice.
That fish source has good fish and another large order from me next week after this American turkey day thing is over. Nice folks to do business with.

I have heard the same from some person on http://www.corydorasforum.de. Wasn't it you? By the way, I know one man here in Czech republic, who spawned C. schwartzi hormonally. But he says that they had few eggs and he give it up. I also know that Ian Fuller bred them, but only accidentaly. I would say that the fish need big changes of chemistry, because the water in their habitat becomes quite acidic and very soft during the rainy season. However, I tried it with my group of schwartzi unsuccessfully.

Hi Cartouche,
No it wasn't me. I always go by apistomaster. I'd just read of this working for someone but I'm not sure where. Now seems to be in the middle of the more seasonal Corydoras spawners, so I would be willing to try most anything that might trigger the C. schwartzi into spawning.
It would be a nice accomplishment to have under your belt. Also to have F1 fry for future breeders would be a step in the direction of making them more easily bred if they follow the trend that many other difficult to breed fish have followed.

So, it seems that you must buy pandas, if you want to spawn schwartzi! 8)

But don't be too optimistic as for a F1 generation. Eric Bodrock spawned C. robineae several years ago and he also hoped that the F1 fish would spawn easier. They didn't and eventually he sold them all, including the adults, who have never spawned again.
