The banjo will be fine for you and it will not eat any of your fish,they will eat tiny fry but thats it,i dont know what size snail they eat,to be honest ive never actually seen my two eat anything but theyre both as fat as lard and the tank they are in gets no snails.
If you can get them get at least two,youll see more of them if kept in a small group,theres even the slim chance of breeding.I think once you get some youll grow to love them,there isnt many fish that you can pick up with your hand and stroke is there?
As for being scared of catfish why? I can understand being scared of snakeheads (mine has bit me enough times) or pirahnas and other fish with big teeth but almost all aquarium cats are harmless to humans,think of them like new newborn babies,theyre as ugly as sin but you luv them anyway
