Are you serious? Have you given any thought on how to clean the thing on the inside? Tropical fish only show their beautiful colours when they feel at ease. Can't see them being at easy in that setup.
For that sort of money you can get a nice complete 120-150 litre conventional setup together with some fish, which would suit the fish much better.
Also, have you thought about what you are going to keep in it! They are sooooo small and you CAN NOT keep the three fancy goldfish in them that they show on the box!
Go to you local aquarium centre and see what you can get for the same money....then join a decent fish forum for advice on cycling and stocking....
Ebay also have some real bargains on second hand tanks...I should know..I have three! lol
there are some other stylish options including large cylinder tanks and others that can look equally good and are a lot less trouble... if you want to spend money on a biorb get the biggest one and just have a few little neon tetras etc really any home for living things should be chosen with their welfare in mind rather than looks
