i feed them nutrafin flakes, and they are in schools and is heavily planted thats about it really, they hide when light is off but are very active during day, the x-rays expecially.Tetrafan would you mind telling me what you do to get your tetras to be active? I think I did almost everything I've added several plants, I've added more tetras to up there schools but still nothing they contine to hide and some of them go to the extent of not eating when the light is on and when I feed my pleco thats when they eat his food.
