My poor guy.
Photon had only been with me for a little over two weeks. At first he was okay, eating and flaring ... but then he started to stay around the top of the tank, listless. This morning I decided to check on him and he had passed onto the Waters of Heaven. Whatever he had was too late to treat, and I do feel bad about that . . . but he is in no more discomfort. He's swimming with his brothers and sisters. Swim free, little one.
