Good presents for my younger brother?

My brother’s eight, has no responsibility, likes to play, and likes video games, but he is fascinated by animals. I saw these things, like “Sea Monkeys”, but they’re called “Triops (longicaudatus)”. They are like a type of shrimp that you hatch and feed, and they don’t require much care at all. I think he would really enjoy this, but I was wondering if it is a good idea? And I did think of a ant farm, but our parents would kill us if they got out.

Here is a link to the product I want to buy: http://www.discoverthis.com/triopsdlx.html

It also has all 5- star reviews, and good comments.
