For the love of God I think Sarah is trying to give me a heart attack. I came home and found her lying on the bottom of the tank. My tapping on the glass didn't seem to rouse her nor did Sparkle's nudges. Now 10 minutes later she is swimming up a storm in the tank. (I'm actually starting to think Sparkle might be a boy, not a girl. Perhaps Sarah was doing the old, if I pretend I'm a sleep maybe he will leave me alone.)

Ohh God, she's back resting on the bottom again. This is going to be a stressful evening. I'm hoping its just punishment for my leaving them alone two weekends in a row. I've been a neglectful mummy.
