I had bought the small Aquarium for special screw. The structure is quite easy and it looks quite nice out but the lighting is way too dark. This pool should not be placed in a dark corner otherwise, I am afraid, used plants would go. Nor is it possible to switch on the light to bring, so you have to remember myself, the light on and to switch off again. For one or two worm likes rich but otherwise it really is available only to purely decorative purposes.
