:'( I have recently added two new male swordtail to my tank. Previously there were only 3 tetras and 4 zebras in there. (30 gallon tank)The new guys are not doing well. I never see them eat they hide behind the same plant all day long and their color is fading. They just lay at the bottom all the time. Any advice on how I can help them adjust better. I have added stress coat and some of that "bacteria in a bottle" stuff but there is no change. Poor little things I hope I can help them some how!
