These guys are great!!! They're closely related to Synodontis Catfish, but have more gill rakers due to them being filter feeders. The 'moustache' is a pair of modified barbles that guide the food into their mouths. They're like miniature Hoovers and are surprisingly fast moving when feeding. They enjoy frozen bloodworm and daphnia as well as catfish pellets and other small bottom feeder foods. They will get to 12-14" in length (they're approx 3" at the moment) but are real slow growers. Like almost all of the Mochokidae family they can live for between 20-30 years, possibly longer!
