I just came across these bizarre fish. They are apparently quite common in public aquariums, fisheries and in Japan, juveniles are used as novelty gifts or something like that. Lumpsuckers have inspired Ponyo. They aren't good for home aquariums.
Finnish aquariums don't have them, but some Swedish ones do. Yay!
