Sad news tonight. C-3PO, the Lilac Festival fish from last year died earlier this evening. David suspects that the new fish must have brought some kind of disease with them. I feel so bad. I should have kept him isolated in his own tank. Ian feels bad - he and I both cried. If the remaining ones go, too, I promised Ian we'd get more. I guess that's the price of fish ownership. They do tend to die. I'm sad about it, though.
