How do you explain this to your 4 year old??
The fish jumped out of the tank ... and died. Seriously. Mattias came into our room this morning and said, "Mommy, Luigi's on the carpet." That's 2 pets in a month ... and the first fish that died, Guido, had his fins eaten by Luigi, and sank to the bottom (rather gross).
I think Luigi's water got too hot with the heat of Mattias' room ... either that, or he found no reason to live anymore *smirk*. You know how tough a fish's life can be.
So sad ... and there were tears again - and a small "flushing funeral".
