Hi everyone, Ron Oldfield here. I just want to clarify that the specimens we studied were known with certainty to be Cuatro Cienegas Cichlids, Herichthys minckleyi. We realize that some specimens look similar to Texas Cichids, Herichthys cyanoguttatus, but they were not Texas cichlids, nor hybrids of unknown lineage. They were originally collected in Cuatro Cienegas by Ad Konings in 1993, and they were then acquired by Dr. Dean Hendrickson in 1995 (and we have dated documentation of the acquisition of the specimens). That lineage was maintained by Dr. Hendrickson for 22 years (from 1995-2017) in aquaria in a lab that contained no other cichlid species. The specimens I bred were obtained from those aquaria, not from the outdoor ponds described in the video (although those ponds were isolated and not susceptible to invasion by other fishes). If you would like to learn more about this fascinating species, or if you have any questions about the origin or authenticity of the specimens shown in photos on social media, then you might find the following articles interesting. In this issue of the Ohio Cichlid Association newsletter, there is a summary of the research we did on Cuatro Cienegas Cichlids. It shows several photos of our fish: www.ohiocichlid.com/members-only/monthly-bulletin/june-2018 This is a press release describing the sneaking behavior that I observed in my home aquarium (which will be discussed in part 2 of this Mad Aquarist interview). This one also shows several photos, and videos, of our fish: thedaily.case.edu/case-western-reserve-university-researcher-discovers-fish-uses-sneaking-behavior-stealth-mating-strategy/ This is the article that we published in the scientific journal Hydrobiologia. This one also shows several photos of our fish: www.prosanta.net/docs/hydro.pdf Finally, we archived dozens of photos and videos on the Case Western Reserve University public digital archive, Digital Case. Many of these videos were shot by researcher Brook Swanson in Cuatro Cienegas. Those can be viewed here: digital.case.edu/islandora/object/ksl:HminckBehavior
Hi Dr. Ron Oldfield I have 4 of these I obtained from a good friend of Chris Biggs...Mr. Mike Drawdy. I am not sure on the sex of my 4 specimens, but Mike did mention that these fish came from your lines. So I am taking good care of these fish and hopefully can keep them going for my small part of the preservation of this species. Thank you for your work and I look forward to Chris posting more videos on this subject
@@themadaquarist I will be tuned in for it for sure. I actually ran across some of the articles Dr. Oldfield published in his links above. Thanks to you, I have a face to go with the articles. I was also unaware that the University is in Cleveland, Ohio. I have a bigger to do list now for the next OCA Extravaganza! Sure wish I had known all this info before I came to the show this year...cant wait for next November!
Bucket list All the small CA species+ Vieja breidohri 'Angostura ' & Herichthys carpintis Rio Honcho so I can coculture them with Xiphophorus. Juan Miguel is such a resource as are you,Biggs
Hey Dave! I saw you briefly at the auction, but you were walking in the opposite direction and I wasn't able to catch up with you. I will stop by the shop soon!
Thank you so much for this video! I picked up four of these guys from Imperial Tropicals when they made them available. I'm trying to learn as much about them as I can but info is very limited. They are all doing great! About 3.5 inches now and packing on weight. It appears that I have one male, and three females. Would you happen to know the max size for this species? Just wondering if they get as large as other Herichthys.
Hey Brother Biggs, reminds me of the variations within Darwin's Finch. Another species we can't have down here. We do however have the more common H. cyanoguttatus to play with. Enjoyed this one, cheers Jason
Just when you thought it was safe to go back in the water, yep I'm back Brother!. Someone has to keep you in check. Biggsy, the Expedition was a major success, with a world first + amazing underwater biotype footage in HD, lots of fish up close. It was over and above what I expected. I uploaded Episode 1 last night, but it is full of glitches, that I cannot fix until my editor returns. It is mostly logistics before setting up camp, but there is a sneek peek of some of the fish coming in future episodes. Please, don't drop a comment as I will be deleting it and will reload a remastered version. I'm only keeping it up, until some family members overseas view it, then it's gone. Oh yeah, there is a special something, just for you! in a coming episode. Do you remember asking me to get you a certain something? I bloody did it! I never thought I would see one in the wild in my life time. Any idea, how rare these things are? Got up close and personal ( little to close actually, and she let me know ) he he, well that's me. I'll be sleeping for the next week lol, and catching up on your back episodes. HAPPY NEW YEAR BROTHER! Ps. don't forget you were invited on this trip.
Awesome species especially when you get to observe them in the wild like I did in February. Here is a video I made of them. ruclips.net/video/9b9_XrirsZI/видео.html

Dr. Ron. Mic drop!!!!
Thank you my friend
Exactly the reason for doing the video to get the nay sayers to just stop! Thank you very much Ron

I Like Midas, Red Devil, Arrow, All Herichthys
All epic and amazing fish and definitely worthy of aquarium space
I Wish I Had The Herichthys Minkleyi, Cyanoguittatus, Carprintis
Having a fish bucket list is a major driving factor to keep interest my friend... one day
Bucket list All the small CA species+ Vieja breidohri 'Angostura ' & Herichthys carpintis Rio Honcho so I can coculture them with Xiphophorus. Juan Miguel is such a resource as are you,Biggs
Truly kind my friend, thank you
👍🏻💪 Hi Ron.. been awhile. Missed you at the show.
Good stuff Biggs

Thank you kindly Dave. BEST IN SHOW DAVE!
Great video informative 👍
Thank you very much
👍
Awesome video. I love when I have to look words up while watching... 🏆 I want more nerdy scientific stuff
Stay tuned

5-6" would be considered a large adult
