Ha! Few things will work with a sub-adult and adult wyckii in a home aquarium and even those, sooner or later will get whooped.
It is a cool cat! I have been tempted for years to get one but they are rare and I've never come across one. There are about 6-7 occurrences on my memory that I saw someone report seeing one or actually getting one.
Once, before I knew better, I bought a pair of "them" that turned out to be Platysilurus mucosus, which never grew beyond ~8" (and do not have the protruding lower jaw but otherwise look much like miniature platyrhynchos to my untrained eye).
