Well, my poor Alpha finally crossed under the rainbow bridge earlier this week. I'm not sure when, but I suspect it was Wednesday or Thursday (I was out of town and my mum was caring for him and my shrimps). She says she never saw the poor guy in his tank and I found him half-eaten and tucked away in a dark corner in the back of the tank... I hope he went peacefully as it was a long time coming. I'll miss my beautiful boy forever.
