So this mOrning before I left for work I went downstairs and turned on my laundry room light. It's enough light to allow me to see the tank without interrupting them sleeping. When I looked over atthe tank ibsaw my clown laying in his side in the sand. Normally, he hosts the corner of my tank next to the powerhead and swims in one spot allllllllll night. So this struck me as abnormal. Shoukd I be concerned? Is this normal? He immediately swam straight up tithe top of the tank and then back down then back up. And ten went to his corner. Hoping he was sleeping.... I'm thinking about discontinuing the moon lights on the tank. Maybe it's too much light And the fish aren't sleeping. Help.
