Curious about the Jelly Cats.

  • We are currently upgrading MFK. thanks! -neo
I've read trough most of the links you sent.now. Thanks Thebiggerthebetter. What do you guys think would be a good adult tank size for the apurensis? Im thinking something like 2 x 1 meters ? Maybe more? Am I completely off? ( im new with the larger cats )

You must have seen my big doubts with the species ID reflected in these links and that it appears to me the genus needs a re-work or at least a better explaining of their revision for us laymen...

You also must have seen that Yellowcat (who you should know now is another great expert on these fish and Pseudopimelodidae in general) says his C. apurensis was 2'.

Hence, I'd say 4Lx2Lx1.5L at a bare minimum = 8' x 4' x 3' when it is an adult. And only because they don't require much space to swim around.

Yes, ok. I read it. And I saw he stated the minimum tank size too. I asked for a good tank size. I read all this on my old mobilephone, so might have missed something.

IMHO, good size would be anything significantly larger, especially in the footprint, than the aforementioned bare minimum...

... again, keeping in mind my ID woes and that I personally need to see more cases than just Yellowcat's showing that apus grow to 2'. I really hope he chimes in. If not, please, PM him, Karl.

You can also write to Wolfgang Ros on his website/email. Wolfgang and I discussed my 3 fish on Waterw*lves three years ago but this forum is dead. Perhaps he will think it worthy to join MFK and enlighten us.

Ok, thanks. If my comments, sometimes come out slightly aggressive, like before, its because English is my second langauge. Didn't mean to put it out that way :)

? You have not caused even a shade of displeasure to me :) All is good on my end.

I apologize if I come off grumpy/cranky. I am not but my written communication skills leave much to be desired.
 
I bet it won't be last :)

No. Fowleri was not one of mine three (Yellowcat had it as you must have seen).

Fowleri is a bit easier to tell from the apu and the nigricaudus owing to a bit different head and body shape/proportions. It is the apu vs nigricaudus that I am thoroughly confused about as well as a suspicion that there may be more species that have not been described yet.

Thanks Again. Im not yet trough all the articles and threads. Theres alot of useful information. I saw Yellowcats Pictures of hes fowleri, and hes to Cep's fighting. I also saw your Pictures, Again very nice cats, most be wonderful with a 40 x 6' Im just curius. Off topic: What is the stocking list of your large pond :) ? It seems that the key to id'ing the Apurensis, and Nigricaudus, is to found out where theyr caught. Again Wolfgangs articles where very informative, and it was extremely helpful. It seems ive made my about what jellycat ill get. I enjoyed the apurensis, and nigricaudus texture so its gonna be one of them :) I might wait a until im a little closer to moving tho. Dont want them to live in the 140 gal to long :) And you where right, i have another question :naughty: It might be in one of the articles i am not done with, but i dont think so. Is it possible to get them in pairs? I always enjoy having my fish in pairs, but if theyr gonna try and devour echother i doubt it would be much fun ):
 
If you look at the rest of the pages of that thread with my jellies, you will see most of the stock except for obsessive-compulsive hiders like wyckiis, smaller and/or less dominant Leiarius marmoratus and pictus, wallago, etc.

Sexing appears to be easy at larger sizes: PCF: "Females larger and much more aggressive, very distinguishable dimorphism by venting especially at larger sizes. "

Breeding in captivity is unknown for all three species.

They are fiercely territorial regardless of the gender. Since my pond was 40' long with lots of line-of-sight breakers and hiding places, mine 3 have not fought too badly but still fought - tattered fins, esp. caudal were most obvious; no significant wounds or other abrasions on the body. Fed side-by-side though because I fed all in one spot. I think the fights were nocturnal when they all came out to stretch their members.

I think they are the kind of catfish that come together only for the period of mating in the wild. Other times, they each have their territory. Whether there is an overlap in the wild of, say a female's and a male's territory, IDK. Would not be surprised if there was, kind of like male tigers have no territorial overlap with other males but females' territories are much smaller and several of them usually overlap with each male's enormous territory.

You cannot have 2, or 3, or 4 in a small tank - each of them will think the whole tank is their territory. The larger they grow, the larger territory they claim. On the opposite extreme, I've seen 10-15 of ~6"-ers in a 20-30 gal at a LFS staying peaceful, which is not surprising. Same is true with say having 10+ aros in a tank or pond - aggression dilutes to the point of near zero.
