I reduced the white light awhile ago before i got my BTA, should i start increasing it? I have a fluval sky led i think, so i can change White, and rbg. Not sure good settings for each light . This is whole tank
My first thought was looks to be reaching for more light, though I agree sometimes they just take on different shape.
If you can ramp lights up slightly I would try that and see what happens, but go slow on that.
