i know this may sound a bit odd, but i think my mandarin goby drifts around when it's asleep. as if it was sleep swimming. during the day it usually roams around picking at rocks for pods and then returns to its usual spot in the tank.
but tonight it did the weirdest thing. it started swimming near the surface of the water and started getting blown all over the place by the powerhead. i thought the thing was dying so i put my hand in the tank to gently hold it in place. It didn't react much at first, then it gently swam out of my hand.
later on i see it gently swimming against the current of the powerhead near the surface of the water. so i thought "ok well he's strong enough to swim against the current."
then the light cycle for my lunar LED's turned off and the goby kind of woke up, and started swimming towards the bottom of the tank and then all of the sudden darted towards its usual hiding spot when i approached it.
i have a 60gallon that has been cycled for close to a year and the only other fish in the display tank with the goby is a lawn mower blenny. asides form that is a 40gallon refugium with three damsels in it and a red sea protein skimmer. I see it actively roaming the tank during the day since i got it (2weeks ago) and i do see pods walking around on the glass of the tank and on the live rocks as well. so i know it's food source is no where being depleted.
this is the weirdest thing i've ever seen. i know clown fish sleep. but i've never heard or seen a fish sleep swim.
has anyone experienced such behavior with their green mandarin goby?
I had my water tested a few days ago and everything seems to be in check.
