what would it take

[sequoiacat, posts: 90]

to get a species page for a catfish that is found in the aquarium trade only and is a hybrid between tigershovelnose species and leiarius marmoratus?

[Birger]

Make sure it is not one of the hybrids already in Pimelodidae

Send a picture or pictures with an explanation, following the directions in the link below for sending images.

I totally support this initiative. I've kept and keep these guys too. But one thing to beware is that I've recently stumbled on two slightly differing kinds: one is likely a TSNxL.marmoratus or longibarbis kind and the other is TSNxL.pictus, if I had to guess: viewtopic.php?f=7&t=36214

I don't think they are in Cat-eLog. I am pretty sure. Not under Pseudoplatystoma or Leiarius for sure.

[sequoiacat, posts: 90]

viktor since ya can tell the difference if it is a L.pictus or L.marmoratus hybrid look at the one I got should be a pic of it and two L. pictus within mycats page.

[Viktor Jarikov, posts: 2275]

Oh! Surprise, surprise! You're Aquaculture on MFK. I just saw these photos today for the first time in Catfish Media Lounge. I'm inclined (and inclined only), judging from the spotting pattern of your 32"-er, it may be the standard TSN x marmoratus/longibarbis. But really, a side shot is needed with a nice view of a dorsal fin.

Yet, again, I cannot claim I am right or I know the difference. I only proposed that the dorsal may give away the difference - it is but a straw-man proposal. I needed this to be validated by the PCF experts but so far got no response (in the thread linked above). Either they didn't see it/didn't wanna see it (I don't expect any one to ) or they don't know.

OK cool thanks, the side pics will have to wait till they are moved again or i get an underwater camera. With the species page for TSN x Marmoratus ill use the same format that pc uses and post it here and info can be verified.

Here's what I ve come up with so far:

Cat-eLog Data Sheet
Scientific Name
Pseudoplatystoma sp. hybrid
Common Name(s)
None
Type Locality
No locality.
Synonym(s)

Species Information
Size
900mm (35.43") SL. Find near, nearer or same sized spp.

Identification
Appears to be a hybrid of Psuedoplatystoma and Leiarius sp., possibly L. marmoratus and P. tigrinum
Sexing
Unknown
Habitat Information
pH
5.8 - 7.6
Temperature
21.0 -26.0°C or 69.8 -78.8°F (Show others within this range)

Other Parameters
Requires clean, regularly changed water can become listless and loses appetite if a regular water change regime is not adhered to.
Husbandry Information
Feeding
Carnivore feeding on a very mixed and varied diet including earthworms, whole prawns, mussels, floating sticks/pellets and catfish pellets. In their natural environment they would feed upon other fish.
Furniture
Large, spacious tank with open space for night time cruising. A large shady bogwood root or pipe that the catfish can retreat to during the day is also required. Ensure the heater is in the open and not in a place where the catfish may try and hide.
Compatibility
Ideally suited to life with other large fish. These catfish are predatory and will eat smaller fish if hungry.
Suggested Tankmates
Other large catfish such as Pseudodoras, Oxydoras, Pterodoras and Megalodoras.
Breeding

Good job but I think Birger was suggesting to send this info and good pics to him or PCF.

I can provide pics too, just let me know if you'd like that and when.

As for the slightly-differing hybrid from the MFK (my thread here), you and I can ask 2songbirds, the keeper of that cat, if he'd be interested in donating his pics for a new Cat-eLog datasheet for his cat.

[sequoiacat, posts: 90]

Ya, I figured that he wanted me to send it to him but I figure post it in this forum first to see if anyone wanted to add anything / change anything about it because i would like it to be as accurate as we can get it. Ya any pics would be good i was going to get the pic I have of mine cropped so that it only showed my tsnxleiarius.

[Viktor Jarikov, posts: 2275]

Good plan. Let's see who chimes in. I'd not hold my breath for long though. There is literally a handful of people here who keep large cats AND are active because it is hard to do so responsibly. But you know that just as well as you know the difference between MFK and PCF, having been participating on both. My "gruesome" prediction, we are (pretty much) on our own in this initiative.

*****************SA fish farms ?

Synonym(s)

Species Information

********************mine have been fine at 82 F

Other Parameters
Requires clean,

*****************well aerated,

Husbandry Information
Feeding
Carnivore feeding on a very mixed and varied diet including earthworms, whole prawns, mussels, floating sticks/pellets and catfish pellets. In their natural environment they would feed upon other fish.

*****************There is no natural environment for them. They don't occur in the wild. So, you want to say "If they occurred in the wild, they'd likely preyed on other fish, crustaceans, and be scavengers too.

Furniture
Large, spacious tank with open space for night time cruising. A large shady bogwood root or pipe that the catfish can retreat to during the day is also required.

***************************When small. Large fish does not require hiding places.

Ensure the heater is in the open and not in a place where the catfish may try and hide.
Compatibility
Ideally suited to life with other large fish. These catfish are predatory and will eat smaller fish if hungry.

********************************I'd add they have been claimed by some to behave aggressively/territorially towards other catfish, even not conspecifics.

Suggested Tankmates
Other large catfish such as Pseudodoras, Oxydoras, Pterodoras and Megalodoras.

***********************I'd add at least 1/2 the length of their body.

Hi All,

Are you sure it's not in the cat-elog already? Can you post pics in this thread?

Thanks,

Jools

[Viktor Jarikov, posts: 2275]

Yes, I am, Jools.

see my pics

mid-1st-page - viewtopic.php?f=7&t=34777&hilit=+zungaro

4th pic from the top - viewtopic.php?f=25&t=29488&hilit=pet+catfish&start=60

closer to bottom - viewtopic.php?f=7&t=30764&hilit=+tsn+leiarius+hybrid


Here are 3 pics from fellow MFK-ers (note the first pic is what I naively propose is possibly a TSNxL.pictus due to a clearly larger dorsal):

My sub-adult 15" and 7" juvis - this is what our fellow importer Snookn21 (John from Ft. Myers FL) brings in (my fish is from him too):

Nice work gents

[sequoiacat, posts: 90]

Now how do I get this info posted into the Catelog?
