Hey guys my wide bars are skittish as hell. I've had them for nearly half a year now. They'll come to me and eat when i put food into a certain area of the tank, but if I reach over the top to check my filters or turn on the lights, they just freak and bang into the glass. Their noses are beginning to become damaged. They're about 3 inches and there are 5 of them in my 90. I will upgrade but it seems like its best just to get rid of them because in a 6 ft tank it'll still be the same.. Do you guys have any suggestions to prevent them from hitting the glass so much?
