All, I can say is @#$%^&!!!! This is just unheard of. It may not strike others as it does me, but I have NEVER seen any cross-breeding in the Geophagus species. Just a shocker and thought I would post it up!!! eartheaters.com/phpBB2/viewtopic.php?t=1930 |

Well! Then I don't feel quite so bad about my german ram stealing the bolivian ram's woman! And they had more in there so they could breed with their own kind--did I read that correctly?

Yes you read it right! That was a Geophagus Orangehead and a Geophagus Altifrons breeding, though I don't think this guys thread said if any fry survived. I hope he done the right thing and culled all of the fry or used them as food for other large fish. Thats all we need are more species of Eartheaters to try to properly identify. Sorry for the excitement, I've had Geos for sometime now and never knew they could cross-breed(or whatever the term would be).  |

I'm very skeptical of this. I don't think they would hatch or even be fertile.

I am not the most informed eartheater guy out there, but my question would be why couldn't they. I am only familiar with Africans, and they can interbreed fairly easy. If you have to closely related geo's why couldn't they.

I'm very skeptical of this. I don't think they would hatch or even be fertile. That was my thought, but just to see the Orangehead female lay eggs and allow the Altifrons male to "try" and fertilize them is just amazing to me. But, the guy never said anymore about it so I assume nothing come of it. |

I didn't question it, just out of sheer ignorance. I'm still wondering why wild-caught cichlids are more sought after than domestics! To even try to guess who might breed with who is not something I could do.

Jon - there is no record of my knowledge of geophagus enterbreeding. It is extremely rare to see some even try. It is almost certain that they cannot produce viable fry because it would have happened by now. I'm sure some of the subgroups that are just regional varients can but that would be about it.
Angel - People want wild caught because they are stronger and more genetically diverse. Most aquarium strains are line breed or enterbreed or just weak. People breeding to sell fish do not cull the weak like would happen in nature. In the wild less then 1% of a spawn would live. In the aquariums they do not cull the weak because they are money. Then people buy weak fish and breed them. The fish get weaker and weaker if breeders are not responsible which they are not.

That's pretty cool, with africans a wide array can interbreed which is how you have some ob haps and peacocks

I have never seen or heard of a geophagus hybrid. You haven't either have you Jamie? I've read a lot on geo's and never heard of any hybridization.

Nope, never heard of it, thats why I posted this to see if I was crazy or not! The only two cases I know of with possible interbreeding are the Geo Winemilleri=Geo Altifrons "Negro" and Geo Rio Areoes=Geo Altifrons "Tocantins". Both Winemilleri and Areoes have been discovered in the passed 20 yrs and the two Altifrons I listed were found a few years before them. Both cases have extremely similar traits but I assume enough different ones to be able to call it a completely different species. This could be from possible "interbreeding" in the wild but I have never seen any evidence of it in captivity, that were successful anyway. |

I wouldn't be surprised if both of those end up be the same fish. Just collected in a different laction so they have slightly different characteristics. Until the start doing DNA on these I don't trust a lot of the groupings.
