They look great, such a beautiful fish and I had a similar reaction to you the first time I seen my Ilyodon Xantusi fry born. Very large fry.

Many believe Ilyodon Xatusi and Ilyodon furcidens to be the same fish .

Okay, finally I had some time to do some research into this matter! If anything I am more confused than ever! There are very conflicting evidence on the net about these two species, or one species if you prefer!
This quote is from the goodied working group Ilyodon fursidens page...
"So finally, it is neither genetically nor by the number of metacentric chromosomes possible to distinguish furcidens from xantusi. Considering that in many habitats both trophic forms can be found (even in the type material of furcidens), the final consequence had to be to see both forms as members of one species."

Well finally the mystery is solved. lol. And interesting conclusion |

LOL , I agree very confusing . |

My observation!!!
The Ilyodon Xantusi fry has a distinct black rim of the dorsal fin, which lacks on the Ilodon Furcidens, so now what? I think this is an evolutionary trade. I also read that Xantusi has two forms one with wide mouth more suited for algae grazing, and another with narrow upturned mouth more suited for snapping up insects and inverts. Could it be that like so many of the cichlids, this fish also adapting to the changing environment? could it be that Furcidens is a cross between the two Xantusi? I have more questions than ever!!!

So after doing some further research the only real difference and reason they were putting furcidens and xantusi as different species was because furcidens has a small mouth and xantusi has a large mouth. But both forms have been seen together in the same habitat and breeding. They are just that different forms of the same species. And as previously mentioned by Gabe, the final consequence had to be to see both forms as members of one species. Since furcidens is the older of the two scientific names xantusi is no longer relavent. So I will no longer call the fish I have xantusi and they are now Ilyodon Furcidens.
