Odd Clown behaviors

[Ztrain]

Interesting clown behavior. Saw one of the clowns rubbing up against the back of the tank down in the corner and swimming nose down. Went ohh crap here is Ick. But then the other clown came over and started doing it too. I stuck my phone in between my desk and the glass to get a closer look. Anyone have an idea of what this is?

I had to work a late shift tonight and forgot to leave a light on for them so they were in total darkness for a few hours before I got home. Normally they have been hugging the heater but when I flipped the light on they were out in the front of the tank swimming all random and erratic. Last time I saw this behavior was when the pumps were out after a power outage. I guess the lights would have been off then too. Is this normal for sleeping clowns? The wild up and down and erratic movement makes me nervous. My phone has really good low light performance the room is a lot darker then it looked in the camera.

Are these just the way these fish are at night? These are the first two salt water fish I have ever owned and normally the gold fish just sit there motionless when they sleep. Every day something new with this tank. Hopefully worrying over nothing.

If you don't have already you can a $9 timer for the aquarium light from Home Depot or get a digital one for $20. A lot easier on a hobbyist and gives your tank inhabitants day/night consistency.

I have one of those for the Kessil over the tank. Normally there's a bit of light on in that room from the monitors on the computer at night and leakage through the blinds in the morning. Then the Kessil comes on at 11AM and goes off at 8PM.

Pretty normal, though they look to be fighting quite a strong current.

They swim like that even when I have the pump turned off.
