Yeah it is wierd IMHO how people keep their fish. I feel bad for puting an possible pregnant stingray that about 35cm over her disc in a tank thats 150x60x60cm but its temporary for her. Her new home is finished today.Fully agreed on your points Tobias, that's mystified me since I've been living in Asia. The reasons vary somewhat among different countries here (and different people within a country). Can be space, income, knowledge/education issues etc., but a lot of it just comes down to cultural differences/perceptions.
