wow i cant beleive it, i just commented on how i had nursed 3 tetras back and when i got home from work one of them was dead on the bottom being picked apart by a rainbow shark..... his name was Face, cuz he had a messed up face. Maybe i jinxed him by saying something but when i left for work this morning he was as he always was, normal swimming, no signs of distress at all but when i took him out of the tank and took a close look at him i could see that the cotton had gotten past his eye and into what i beleive was his brain area, im not a marine biologiost though im just kinda sad about my deceased tetra
