I have a memory of seeing a nature documentary from the amazon years ago. In one clip the showed fishermen in a small river caching giant Corydoras. I would say 8-10 inches (20-25 cm in length ) and maybe 6 in height. They never named them in the documentary. It was just background stuff that only fish nerds focus on. They where brown and rather dull.

Every now and then i have been trying to find any info on the species. I have never been able to find any info on it or find anything similar. Does anyone know what species it might have been or have i just dreamt everything.

I am attracted by the though about a monster tank with monster cories :hmm3grin2orange:

I have always wondered if there is a ton more larger types than people know about for the aquarium trade. And also what the locals supply for the trade.

It's very possible you did see that there are still a great deal of mysteries left in the Amazon not sure what species thought

hehe There is a great number of mysteries left here. The last time last an expedition went in to Bosawas they found a large number of new fish species in 7 days.

(lets go there)

Could it have been a brochis? http://www.seriouslyfish.com/species

At that size and color, I wonder whether the mystery fish might be an unknown species of another type of callichthyid - perhaps a Callichthys or Hoplosternum?

Hoplo is what I was thinking as well but couldn't think of the name.

It is possible. It was similar in size and color to Hoplosternum littorale but with a higher body.

No too long/low body. the body should be about half the lenght of the fish.


Imagen this fish but big. the color a little darker

I could see it being a high-fin version of Hoplosternum littorale

There are several large longnose Corys which are less schoolingfish but live in pairs or small groups. Some even are agressive towards their own species.
