Actually, this isn't fish abuse at all, infact they clearly saved the fishes life
why do I say that?
Clearly these people live in a magic house where everything magically comes apart, if they had the fish in a fish tank which has multiple parts it may come apart and all the water would immediately come out and the fish would end up on the floor and die, so they obviously saved the fish and put it into a bowl while they try and figure out why their house keeps coming apart, these are great fish owners that use some quick thinking!
