Chromis acting oddly

[mcs]

One of our five green chromis started to act oddly, stopped eating about two weeks after we introduced a blue throat trigger to our 300 gal tank. The chromis had been in the tank for four years. Other inhabitants foxface, kole tang, and four other chromis. I put the chromis in our OT a week and a half ago. He is not eating and spends all of his time as pictured. Hovering facing top of tank next to glass/overflow. Is there anything I can do to help him?

He looks ok from what I can see physicaly. Was he just hovering in the dt and any sign of scratching or swimming into the power head. Sometime hovering near the top or area of flow like a power head or overflow is a sign they are trying to get more oxygen.

My first thought is some form of aggression. Second may be flukes introduced if the blue throat was not fw dipped. I would suggest getting some black worms, freeze fresh clams and slice them into food,, or other high quality food like Larry reef to see how he responds.

If not I think a fw dip could not hurt, but let’s see if #reefsquad can give more insight before doing that

Blue-Green Chromis are notorious for coming in with Uronema, but since you’ve had him for so long this isn’t the case. However, since they are so sensitive to it, it’s a possibility that the trigger introduced it. Or it could be another parasite.

May not be anything at all, but given the way he’s acting...I’d suspect something is bothering him. I don’t see any physical signs, but sometimes there aren’t any. Hopefully he’ll pull through.
