I'm so very sorry to hear that your beloved Pika has passed There is nothing quite so painful as the loss of special pal like your little fish friend. What a beautiful little boy he was. I hope that time will help to heal your heart; that and the knowledge that you gave him so much love during his time on this earth. Perhaps in a while, when you ready, you will be able to open your heart once again and welcome another fishy into the tank. I'm sure Boo would like that. Hugs to you....so many of us here know and share your saddness. Rest easy now Pika and swim joyfully at the Rainbow Bridge until you and your Mom are together again. Love, Sandra
