hybrid?

Tom · Post by **Tom** » 08 Apr 2007, 19:58

Has anyone seen pics of the TSN X niger hybrid? I'm still not 100% convinced because I didn't realise fish from 2 different families could hybridize.

If you mean Oxydoras niger X TSN, I'm afraid someone is pulling your leg. Or someone has done some photoshopping for the Fantasy Catfish League.

Unfortunately can't find a pic other than on forum below, not sure it will work. These are real, Tropical Fish Distributors in Cleveland, Ohio has/had these fish. If not a hybrid maybe a deformed TSN?

Well, well, isn't that nice for a regular Easter Sunday. I've never seen anything like it. Worse, I can even see why people would say it has O. niger in it. This is beyond weird.
Dorad and Pimelodid fans, pls click the link and scroll down a bit. Have a look and tell us what you think!

The Thais have successfully produced Clarias x Pangasius hybrids, so this is not entirely implausible.

I looked closely at the pics and it appears to either be a totally new genus of doradid or is, as advertised, a doradid/pim hybrid.

Hi Shane,
The problem with being a new genus of doradid is that it totally lacks the spines/thorns alongside the body, the thickened fin spines are absent and there's no bony skull plate either.
Therefore I'd suggest it should be a new genus of pimelodid, for what I see is a TSN with the shape of an Oxydoras, or indeed a hybrid as mentioned before.

OMG....

these things look horrible.
at least to me

sure looks like someone managed to crossbreed a TSN with an Oxydoras to me. there are simply no catfishes in South America wich combine a smooth body with a "sandsucker head" like this one.

cause if there were, you'd get something like a "South American Giraffe nose cat" and you just don't need a new name; might as well need a new family.

but I don't think so; someone with access to a lab managed to play god I guess. another example of science-abuse
this is really bad.

where's a vomit smiley when you need one?

Take a look at the link Jools posted above. That was the same pic I was studying closely.

A possibility?

Does anyone know who this guy is or is registered on that site and PM him. While this may become a common fish in LFS', again it might not, and we should record it in the cat-elog with a picture or three for posterity.

The fish in question does not resemble a doradid in that doradids typically have heavily serrated dorsal spines (which is lacking in this fish):

Young O. sifontesi would look something like this:

which does not quite resemble the fish.

The eyes don't match at all and the fin shapes also don't sit right. I'm all for labeling this as an unknown doradid until we know more about why we think it's a hybrid. Sure, there's a look of about it and if I was going to play God to produce a new SA food fish, I'd certainly look at these two tasty genera, but I'd like to know a bit about where it came from before concluding.

Thanks, that clarifies things. Still an odd beast, whatever it may be.

I could not agree more.

Here's another thread about these creatures:

The website for the distributor who has them is tfdfish.com. they still list them, 5-6"- $25.00 each. I PM'd the gentleman whose pics you saw. He says they're very active, eat like pigs, and not predatory at all(even ignore feeders).

I agree with jools I can see the "look" Pseudoplatystoma in it, its an odd creature, something just doesnt sit right with me, hard to put my finger on it. Seems to me that the eyes are too big to be either Pseudoplatystoma or Oxydoras niger and at least to me the dorsal looks kinda dispropotionate to the type of fish and just doesn't look "right" (yes i know not very scientific but therse just something about it thats odd).

I'm not sure if its hybrid or not, but im in the "hoping its a new species" camp cause im rather fond of doradids.

After a second longer look its head shape does remind me of however the rest of the body is too long and the markings of course.

A good observation, which was also made by sidguppy some posts up. He spoke of of a "South American giraffe nose" (which is Auchenoglanis occidentalis), which makes a lot of sense because the head shape of both A. occidentalis and O. niger look very similar.

heh good point

, didnt notice that sidguppy had already mentioned that... I really should stop reading message boards at 2am

Well, I emailed the distributor asking for pics etc. Even though it appears manmade, it should still go in the catelog. Although I am not sure where.
