OK, after adding the nano sized clown last night and watching him for at least two hours I shut off the lights and turned in. Got up this morning, turned on the light and see the clown on the bottom of the tank looking very slow. He made his way to the other side of the tank behind a rock on a ledge and just sat there. I checked the pH; it was 7.8. I added a small amount of booster, let it cycle in and then turned off the powerhead but kept the eclipse filter on. He seemed to liven up before I left for work but I am concerned. Did I do something wrong? Should I look at getting LEDs for night time? Was he just sleeping? Any advise would be greatly appreciated. :neutral:
