My new six line is awesome. Yesterday he swam in and out of my rockwork and ate both times I fed. Then around 7 p.m. yesterday I didn't see him. I thought he was just hiding but I didn't think he was a hider. Well today I haven't seen him either and am getting worried. I looked all around the tank to see if he jumped and couldn't find him. My top is almost completely covered. Anyone know what is up?
