Oh I was chatting with my friend SJ and she was talking about my fish tank. I forgot to update that the Silver fishes (Tinfoil Barbs) died.
I changed the fishtank water before I left my house on 31 Dec 2009 for the New Year's Eve celebration at Pasir Ris (read here).
They died when I returned home on 1st Jan 2010.
Not sure if it was the salt I put in or I did not put in enough anti-chlorine water conditioner.
Anyways I was sorry for the 2 fishes.
The tank now have only the 2 Luohans.
Goodbye my silver barbs
