If it was getting too much light, it would move away from it. Never seen white bands like that. What kind of lighting do you have and what are the water parameters?
bulbs need replacing and getting that fixed soon T5HO. nitrates still a bit high 5ppm working on it with water changes as well as Ph which is low at 7.8.
Its eating just fine and hosted by my clowns. Havent seen any changes in it really except the white bands more pronounced. Hasent moved either.
