Hi !
Thanks for all those informations !
Indeed, I still own Aquamiroir in Brussels. I went to Ruinemans to pic some fishes, it is always better to have them in sight for a better choice... By looking the aquarium where were stocked a group of Lamontichthys llanero, I've seen this one, totally ...

Here are few more pics... Doesn't look like a Rineloricaria to me ! But netheir like a Lamontichthys... I have really no idea !

Hi,
I've found this catfish in a group of Lamontichthys llanero. The pattern is completely different from the others... like spotted... I haven't found anything looking similar... New species ? Mutant ?
