'sleepwalking' mandarin?

[manderx]

i've had this mandarin for over a year, fat as a sausage. but every so often at night i notice it swimming up at the surface of the water oblivious to everything. swims into the glass and the overflow. sticks to the overflow for a minute, then lazily pulls away. i can scoop it out with my hands without trying over and over. next morning, it's back to normal, cruising through rocks picking and stuff.

whenever i notice this i turn my powerheads off for the night and turn down the return pump so that there isn't as much pull through the teeth. but i'm sure it's done this plenty of times that i haven't noticed. other fish are fine, and i'm confident i don't have a water quality problem (toxins or dissolved O2).

what makes me really wonder about this though is i used to have a mandarin years ago that did the same thing a few times. is this just something they do?

I think it's something they do. Possibly they need to keep moving at night for some biological reason.

how could that be true? Mandarins usually hover, or sit on the bottom, so there's no possible way for that.

That's funny, never heard of it. it'll be fun if someone would make a infrared video footage of this someday!

That's pretty funny...As far as I know none of my mandarins do this. Hope he's not a "sleep jumper", too
