Poor little fishies

We've decided to try to get the aquarium going again. It's only been how long since poor little Richard Hatch (the fish-not the "Survivor") died? So we got some bacteria balls (don't ask, I don't know what they're for but they do something good for your tank) and 10 fish that cost 18 cents a piece. Below is a picture of them. Don't get attached - they are sacrificial fish.
The lady at Petland told us that the water (which has been sitting for quite awhile) will cycle and it will take about a week or so to stabilize and that the first fish we put in may die. But to bring another water sample in in about a week and we'll see if we're good to go or we need some fine tuning. The girls are learning a lesson and I'm not sure if it's good or not. We didn't get the "good" fish because we don't want them to die. So inexpensive fish don't deserve to live? What am I teaching my children? Whatever the lesson, they seem OK with it.
Miss Banda thinks she's a wrap for Christmas. Yes, she slept in here like this for most of the day.

Yesterday, at about 8:30 am, Anna walked in her room and put her hand through the crib rails and patted her mattress then lay down beside her bed. Think she was trying to tell me something?
