Why fighting fish?
Because they can live in a tank without oxygen and hence no need to invest in any gadget. So far, Ryan have not been feeding his fish although he was quite enthusiastic the first few days and mummy have to make sure that the fishes are feed everyday. Daddy was given the task to change the water when it's dirty and Ryan? Well, he's just the pet owner. I don't think we will ever get a dog. Just too much work!!.
