On a real note, I have 7 baby(ish) Oscars currently that are waiting to go in my 700g build, and if I didn't know better I would classify them as loosely shoaling. They are almost always all together, nearly constantly, often fin to fin. TBH they seem much more shoaling than my baby Uaru who are always off doing their own thing away from each other. Obviously your average person doesn't have room to have a group of them, but they seem to love being in groups. That group of water puppies is one of my favorite sets of fish I have! I have 3 Crassipinnis Os, 1 wild Colombian common, and 3 normal tigers.
