Sounds like it's a less than common name. Google, Fish Base, and Planet Catfish don't come up with anything. Any additional details? What color is it? Whiskers? Mouth shape and orientation?
There are several lined catfish, many of which get much bigger than 8-9 inches. Cats with long whiskers tend to be predatory (meaning, any tankmate that fits in their mouth will end up there eventually). Cats with wide, forward facing mouths are usually predatory, mouths along the bottom of their mouth tend to be scavengers. Fish like plecos with their mouth on the bottom of their body and a strong, scaly 'tongue' are raspers--woody debris, algae and corpses make up most of their diet.
