Agree with Oddball. See which one of these matches your fishes: http://www.planetcatfish.com/common/genus.php?genus_id=47 This genus is comprised of smallish (10"-17" TL) giraffe cats.
I can't see the patterning too well on this notebook. It's definitely a Parauchenoglanis sp. Probably one of the more common P. punctatus cats. Awesome find for that price.
Slipped my mind but it could be an Anaspidoglanis macrostoma too.
