is it just my black skirts or are all black skirts scared of light? every time i turn the light on in the tank they hide or goto the way bottom of the tank and stay there until i turn them off. these are the only fish ive ever owned that did that..
most tetras are sensitive to light, some floating plants can help to dampen the light once it turns on, or try turning the light on in the room that the tank is in, so that when the tank lights come on its not so drastic
