Last night, I was concerned because Brooke was not her usual active self. Typically, she's swimming around her 5 gal Fluval Chi tank, having a great time. I found her in her hidey hole, under her bridge, in a darkened corner of the tank.
The light is quite strong in her tank, so I shut it off to see if that would make a difference. Sure enough, in a few minutes, she swam right out, front and center.
Tonight, I tested out the theory. Once again, when the light was on, she was hanging out under the bridge in the dark. Shutting off the light brought her right out, doing her usual laps and swimming right up to my face, begging for an extra nighttime treat.
The tank light is apparently too strong for her to be comfortable. Have any of you had the same experience? The light illuminates her tank beautifully - but apparently, I won't be using it much in the future! !
