Hi,
The banjo catfish is somewhat unusual. Here is the little info I know after a bit digging on the net.
Name: Bunocephalus Coracoideus
Nocternal - never see it move since I got it (no, it's not dead, it appears in different spot every morning )
Possibly the ugliest fish in the shop.
There are a 2 different species called banjo Catfish, but I am sure the one I have goes by the latin name above.
