Title says it all, really! My eight-yr-old DD is very keen on the idea of keeping small tropical fish. I am a complete fish novice apart from the obligatory childhood goldfish. I've had a look on the ThinkFIsh website and am now somewhat daunted, but she's still enthusiastic.
Should I be steering her away from tetchy delicate tropical fish towards something more robust? If not, what's a good starter tank? (We don't have endless space -- or money, inevitably.)
