Giant Agamyxis?

Post by Chrysichthys »

A while ago I saw some fish, just called Talking catfish, which looked like Agamyxis pectinifrons, but were about 8 inches long. Could these have been ? The Cat-eLog doesn't give a size for that species.

They could be either one of the two, since the two species reportedly reach the same max size.

I have seen one (and only one, MANY years ago) that was about 8" TL.

Could these not be Acanthodoras? I've seen some where the colour pattern could be confused with Agamyxis at a glance. A single Agamyxis of that size would be remarkable, more than one would be unheard of.

I'm pretty sure it was an Agamyxis, if it had been anything less ordinary there would have been more of a fuss about it for sure. It was brought into the LFS (when I worked in it) when a guy was clearing out a big tank. I used to spend ages looking at all catfish that came in, in the (usually vain) hope that I would spot something odd.

I'm not saying it wasn't an Acanthodoras, but I knew what one of them was back then and I didn't think it was anything but a big (old) Agamyxis.

No, I was referring to the fish in the original query from Chrysichthys. He mentioned that there were some fish (suggesting more than just a single oversize individual). There are always occasional huge specimens that appear, I've seen Platydoras that could have been mistaken for half-grown Megalodoras, and there was a Liosomadoras for sale once at a BAF that was in excess of 12" in length. I've seen freshly imnported Acanthodoras at around 6-7 inches that were difficult to pin even to a genus at first because they were still a bit 'rough around the edges', which is why I suggested this as a possibility.

I'm almost certain they are Agamyxis; they look identical to it except for the large size.
