Hi All, I've had this gbta for about 8 months now. But in the last couple of months it has really stretched out. It's fed twice a week variants of mysis shrimp and fish. My lighting is AI vega Blues, 9" AWL and the nem is about 13" down. I have the whites set at 80% and the blues at 90%. I just raised all the lights 10% about a week ago but it's still stretched out. I would say its about 7-8" across. You all think it needs more light? Is this normal?
