Megalonema orixanthum

  • We are currently upgrading MFK. thanks! -neo
A lovely looking fish. In my view better looking than actual blue jumper cats. Looks like the naming refers to where they are found but most of them reach similar 5" size. Something which would be ideal for those wanting alternatives to Pim pictus, if only we could see them in the shops.
 
Very cool fish. I've been fascinated by the term "jumper cat" and which species it might be. Your fish is not actually Megalonema orixanthum as that species has a much longer lobe on its pelvic fin. That said, I'm really not sure what species it is.

I concur that the trade name "jumper catfish" has been an enigma for me too as far as the ID.

A few years back I got three from Jeff Rapps that were tentatively ID'ed as Pinirampus piriampu but of course they are not, still 8"-10" today.

So do you believe you have Exallodontus ? The fish many actually know as the Blue jumper cat? That fish is meant to grow to similar size as yours. should look to have a much rounder nose than Pirinampu.
My lfs had some "jumper cats" in a while back and I was hoping they were Pirinampus but when we looked they were exallodontus and were extremely skittish at 4", constantly climbing the walls of the tank.

Quote possibly, even though it wasn't the only candidate for the ID. I haven't pursued the ID, nor revisited this issue as the fish grew because I lack motivation to hunt down ID for smaller, obscure (cat)fish. Having said that, I'd still be very thankful if I was served the knowledge on a silver platter :)

There have been several threads on the "jumper" catfish not too long ago, on my memory. I don't remember details but they may contain some nuggets...

Are you seeing any growth on the length of the pectoral fins?
I wondered from the origins photos if they might have been damaged. The last photo seems to show the fish on the left with slightly longer pectoral fin now
I ask since Megalonema Orixanthum and Amaxanthum both have extended pectoral front lobes as blackbullhead says, but I still think these could be Orixanthum as you originally suggested.
