Hi,

Imo C. leopardus or a closely related species too.

PS Have C. Leopardus been breeded

Yes. According to Hans Evers Corydoras book they have been bred by Ernst Bilke. They are difficult to stimulate, darkening the tank (The method is called "Abdunklungsmethode" in german, i don't know if there is an equivalent in english) finally made them spawn.

Without getting a better look at the head I would say the fish was either C. leopardus or possibly C. gomezi. Definately not C. julii

C. leopardus

C. gomezi

I'm still not totally sure that my identification of C. gomezi is correct but I think your fish is the same species. It may turn out to be a new species altogether. Regarding breeding I don't think it has been.

How do you distinguish between C.Trilineatus, C.Gomezi, C.Julii, C.Leopardus ???

What do you think should I try to do to make them breed ???.

by **Coryman** » Tue Mar 25, 2003 9:12 pm

OK the first thing is that C. gomezi and C. leopardus are longnosed species and there are pictires of both on this thred.

C. trilineatus and C. julii have also been covered on Jan 9th and again on March 3rd.

This C. trilineatus / C. julii thing has been bugging me for years. The only way to prove which is which is to know exactly where they were caught.

When viewed head on C. julii are quite slim and not at all stocky looking like C. trilineatus. Exporters in South America use the name C. julii because they get more money for then than they do for C. trilineatus.

True C. julii female,

C. trilineatus

One other point between C. julii and C. trilineatus is that when viewed from the front C. julii are slightly compressed and C. trilineatus are very rounded.
