I used to name my fish, but ever since a heater mailfunction and monster, baby, lady, angel and valentine got cooked I just can't name them. It seems to hurt less if I don't name them and they die. But there is the occasional one that creeps into my heart. I have one guppy her name is miracle. She was found weeks after I got rid of all the guppies in my tank when I did a filter clean up. She was amongst many of her dead siblings so hence the name miracle. I have my big girl she is my biggest bristlenose female and then My big boy, you guessed its my big bristlenose boy. I also call her and him my "meisiekind" and my "seuntjie" which is just the afrikaans for girl and boy
