We have replaced our goldfish with these small sharks and two fish my husband has told me are related to alligators. I am very happy for two reasons. Firstly the goldfish had started eating each other and its quite disgusting to watch the Hannibal style antics whilst trying to eat my dinner. And two I always dreamt of having a miniature shark. Sharks are one of my favourite animals. They are so graceful and agile, through the water but also deadly. I think they are beautiful to watch.
