I went out and brought 3 new baby gbr and one of them started hanging out at the top. I did a water change to see if it would help and then a second one started hanging in the top third of the tank. They look very healthy and no physical changes. Levels are ammonia:0 nitrite: 0-0.25 nitrate:below5. Any help will
