mine is definitely a 4 line, it looks like the one from the description, not the 2 spot.

i'm sure its a pim, because i got it from a pet store, i followed the link in the second response, and it was very helpful. right now its living in a tank with bala Sharks, rainbow sharks, an albino rainbow, and a plecy. needless to say it rules the bottom.

not really sure where this goes, but i've been searching the internet for information about these catfish because i just got one for my boyfriends new tank, and i dont know anything about them. does anyone know a site that would be helpful?
thanks
