Found Neptune dead in his tank this evening with a bloated stomach. We sort of had an inkling to what would eventually be, cos he could just not hold himself at the top and kept getting into a vertical position. We thought it could be SBD and tried to feed him a pea, but he would have none of it.
Neptune was our first and best pet. He was great friends with my wife and daughter and would always come swimming right up, whenever he saw them. Seeing him lifeless at the bottom of the tank was too much for my 5 yr old :(
She sort of cried herself to sleep today saying, 'Why does everyone have 2 fishes and I have only one?'
R.I.P my little buddy. You gave us great joy in the short time you were with us and we hope we made your life comfortable too. If you ever wish to come back in some other form, you know our door are always open for you. Adios!
Thanks to Elmofish, Elena, AngelicScars, JamieTron and dr2b for all the well meaning advice. You guys are great!
