Just happened in my newly cycled tank I have a clownfish and a watchman goby and pistol shrimp will they be okay in complete darkeness I just taped towels to the side of my tank to keep the light out to stop the algae from growing and I’m also gonna keep my lid light off, I was gonna do this for like 2ish days to try to kill the algae off, are my fish gonna be fine with no light and will this method kill off all the algae?
