hey people, i have my 55 and it seems the fish are having a hard time in the water...rapid gill movement and not much swimming going on.lost a rose barb and am fairly positive a danio is on its way out..i tested my PH 7.2 but other than that at this point i have no testing equipment, money sucks and it takes 20 bucks just to get to the fishstore..the 55 is planted and has eco complete.undestocked, and plenty of clean up crew, clear water, water is less than a week old...i dont know whats up really...any help is appreciated...
