I have a branching leather that started to wilt. I had turned down the flow to help acclimate some new fish, and I changed the light in that end from 2 aqueon hood leds that came with the tank to an AI prime 1 6 HD i had been waiting for. I thought it might be from the flow getting turned down, so I put it back up yesterday. Today, it still looks very wilted, and a little greenish.
