I am glad, however, that I asked this question. Thank you for reminding me that they are entirely different species! Post by snowball » Sun Jan 29, am Ian, or anyone else, what's the chance of Corydoras adolfoi and Corydoras concolor interbreeding?
I am planning on putting six adolfi in a 60l 2' tank on their own to try to breed them, but I just picked up a few conoclor to take my group to five and was thinking of putting them all in the same tank together.
While I imagine it would be easy to spot any hybrids as they grow, obviously this is something to avoid. I've noticed that the concolor have a dark stripe through the eye much like adolfi and wondered if this might mean they two species share a closer ancestory that might make interbreeding more likely than between corydoras with different traits, ie those with speckled heads. Post by Coryman » Sun Jan 29, am To be totally honest i you are putting at least 6 of each species together and there are both sexes of both species I don't think there will be any problems.
For C. Post by snowball » Sun Jan 29, pm Thanks for your reply Ian. The new concolors are still too small for breeding so I don't expect anything to come them for a while, but the local tap water here is very soft which should help. Curiously, in the 4'x2' community tank most of the different species of corys seem to have their own spots and rarely mix outside feeding time, except the adolfi and concolor which share the same corner and happily line up together - they make a great contrast.
Post by Coryman » Mon Jan 30, pm C. There are three similar species, which come from southern Brazil, Paraguay, and northern Argentina, they all look very similar to each other in colour pattern and it is almost certain that because of this similarity they have been mixed together in fish farms.
Now having said that I have not come across any report of these naturally crossing with any other species. I know they are being manually manipulated in eastern Europe to produce a strain with long straggly finnage, which I may add to me looks as natural as a penguin in a desert. Re: Will Cory species interbreed or hybridize?
Post by SilverWings3 » Thu Jan 05, am I actually have one cory-Catfish that appears to be a mix of emerald and julii. I did buy him from petco, in a tank of other julii catfish. Though my other 2 I bought from petsmart. He gets along with my other 2 catfish just fine with the exception that he is a bit more active than them. Is also get more catfish but I only have a 5. The only thing that seems plausible is that he is an interbred cory-catfish. I had no idea what gender they were, nor did I specify to them, or did I think they could tell either.
Just now, I noticed in the tank that there was about a hundred eggs on the tank side. BettaFishMommy finkids make me happy Mgamer20o0 BobsTropicalPlants. Jun 4, 31, 19 89 www. Cerianthus said:.

I've got albino and bronze aeneus. Instead of forming one big school- they segregate themselves into the bronze gang and the albino gang. Same species- but they seem to stick with those that look like themselves.
When the bronze females lay eggs- only the bronze males seem interested in fertilizing them. Perhaps if you only had one or two of each they would be more likely to go for other species and hybridize- but they prefer to mate with fish that look like themselves.

I had a batch of smudge-spot x panda cories. They now live in my Dad's tank. I have one in my main tank that's evaded capture up until now. Generally hybrids are infertile so it's unlikely they will breed themselves. Akasha72 said:. I didn't know cories can live that long! I thought roughly 10 years. Byron Fish Guru Tank of the Month! I concur with most of what has been mentioned. Many Corydoras species are more likely to hybridise in the artificial confines of an aquarium.
Species that would never even meet in their respective habitats, when forced into close confinement, may react differently from what one might expect. While phylogenetically it now seems that there are nine distinct lineages within the "genus" Corydoras , meaning nine different but related genera--and most will maintain that fish will not hybridise across genera--the lineages in this family Corydoradinae are obviously very closely related. The three " Brochis " species for example are now within the genus Corydoras , because they share a lineage with two going from memory, think it is two other Corydoras species and are not distinct on their own, in spite of their external physical differences.
I am not aware that the "laser" types have been described as distinct species. They still retain the "C" number without a scientific taxonomy. Ian Fuller has written that there are differences in the fry, suggesting distinct species, but again I am not aware that this has been determined "officially" by ichthyologists describing the species and this has to occur. Corydoras aeneus has such an enormous range over the northern half of South America and onto the island of Trinidad that it is highly unlikely this is one distinct species, since these many populations are geographically isolated; though whether there are distinct species, subspecies, or geographical variants, I am not sure as to my knowledge this has not been sorted out.
