I wonder, how long could live fish from this family, especially two species:
* Microglanis iheringi (I heard about real "Matuzalems" ;)
* Batrochoglanis (Pseudopimelodus) raninus raninus
I've these guys in my tanks, so I'm very interested about such data

Of course, any informations about other catfish species/families are interesting too
due to my interests
