Mandarin Goby acting funny.

[COPE45]

Hi I recently got a mandarin goby. He went in and seemed great, was clearly eating copepods all day. Then all of a sudden after a few days he stopped and just went up bobbing in the corner.

I read that this was normal behavior to do at night (it’s doing it all the time). I also read that this can be a breeding behavior. My concern is it’s doing it all the time and I haven’t seen them eat in about 5 days now. I thought maybe all copepods were depleted so I got more and put them in the tank two days ago. Still nothing, no eating just bobbing in the corner. Sometimes near the top sometimes halfway up. Seems and looks healthy otherwise.

Anyone have any ideas?

This fish has become very thin and has either stopped eating or has internal issue and becoming weak as they do when they get this thin

Is it in an observation tank? I really can’t answer your concern as I’m lucky to see mine only as the lights dim out in the last 2 hours going over the top of the rock structures

No it’s in the main tank. First he was nowhere to be seen except for eating but now he’s just sitting in that corner.

Unless you can get it eating, it will fade away

Got it eating again, found someone local who has a more established copepod population so I’m gonna give him to them. He’s eating now so should be strong enough to make the move.

Last night one of my on timer lights came on in the middle of the night. I went to living room but noticed something odd blowing around in my tank. It was my mandarin goby. I put the white light on and his face was all white and his body pale. and he was just fluttering around in the current. At first I thought he was dead but his little fins were fluttering like he was fighting the current. Since I had just added water, change filters and added Prime and stability, and an algae wafer for my rock blenny, I was sure I killed the poor thing but didn't know how I could have.
This morning feeding he wasn't there and neither was my watchman. I was so sad. I just fed the remaining fish and got ready for work (I do an hour of white light in the morning and blue until I get home at night) Anyway; was just reaching to change the light when both the watchman and the mandarin, came scooting out the rocks. The Mandarin was so bright. I almost cried. Do you think is was mating related?
