Sea Monkeys
Rhiannon is a clever kid. She has realised that nagging for a dog hasn't worked so she has downsized... to some Sea Monkeys!
She bought them about two weeks ago and they were just a tiny packet of dry powder. Within minutes of putting them in their tank a few had hatched. Two weeks later we can see lots of these little things wriggling around the tiny aquarium. 
Rhiannon is in seventh heaven! They get fed once a week and will eventually get to 19mm in length. I have already had a nightmare about them growing monstrously big and breaking free of their tank and taking over the kitchen.Whoever said pets are easy!
