Hello Mats, No offcourse you are absolutely right, I don´t wish to harm them, I just thought that the confinement and not the water quality could be a size restrictor factor like in the case of Koi carp and goldfish.

Going back a bit to the original question, does anyone have experience with keeping Clarias ( ex. c. batrachus ) in a smallish tank? Have you experienced that the fish grows quite large anyway regardless of the confinement or that it has restricted its growth?

Thanks
