A smaller relative of the Giraffe Catfish from West African rivers from Senegal to Chad. The aquarium no longer displays this fish anymore since 2017, despite how rare is it.
@Nandito Yeah, especially the fact they they successfully bred two rare native freshwater fishes: the Toba Mahseer (Neolissochilus thienemanni) and the Kelabau Barb (Osteochilus melanopleura)
