Re-re-re-re start

This summer, I was looking for a project that all three kids (ages 6, 4 and 1 at the time) could participate in. After hunting around, we decided to start up a fish tank. We read about creating a healthy environment for the fish. We bought a tank on craigslist, and the kids carefully selected rocks and plans to make it beautiful. We started with three fish - a zebra danios and two guppies, as recommended by our local pet store. Once we kept them alive for a few weeks, we added a few more fishes. Since then, we've had our ups and downs.

A fiddler crab named King Arthur only lived with us for a short 4 weeks before he died.  He really belonged in a salt water tank, but the pet store didn't tell us that.
