A Mexican ID puzzle for you all.
« on: March 10, 2019, 09:12:27 pm »
Since I was last on here I have got married and I went to Mexico on honeymoon. Obviously would be a shame to go somewhere like that without getting in the aquatic habitats. The easiest way in was through a hole in the ground with a nice swim through the cave system to get out. I took these photos in a Cenote and I would be intrigued to get an ID. These fish appeared to be blind as you would expect. Not much info on water type, except soft and bloody freezing!

Cheers  *cheers*

    After viewing your pics I think I'll just stick to fish in tanks, it looks like a seriously scary fish,  *blink*

    I should have added, they ranged from 3-5 inches. Pics make them look large! Not scary at all!

    It's certainly a puzzling one!Definitely looks like a catfish to me.

    It's got some sort of eye, even if it's non-functional, so I don't think it's one of the truly blind cats in the genus Prietella or Satan. It seems to small too be an Ictalurid, though I suppose it could be a young one.
    I suggest posting on Planet Catfish :-)

    I reckon it's Rhamdia Sp. but not sure on their specifics. Where they were found there was usually light filtering from above to I'd be inclined to agree that they're not completely blind.

    There was also a Characin looking fish, but not the blind cave fish. Almost like a lemon tetra. Cound photograph them though. Too quick.

    From the adipose and caudal fins it appears to be a Rhamdia species. There are 9 of them in Mexico. Whereabouts in Mexico was it?

    I’m not up on Rhamdia but the commonest in Yucatan cenotes seems to be R. guatemalensis.

    Looks like a good shout. They appear to be kicking around the hobby a tiny bit as well but not much info on them.
