After I did a 50% water change on my 120 gallon tank because a nasty brown foggy cloudy water both of my bgk have been laying on their sides and breathing hard... Did I do something wrong??
darn!! 70 is too low?? i dont even have a heater either.. the water has been on 70 but they were doing fine before hiding in their favorite spots.. ive only had my tank up and running for about a week and a half.. i changed the water from over feeding it got brown and foggy..
