10+ Year Old Yellow Tang Struggling

[Jay Hemdal Verified Community Expert]

Physical move from old tank was late June. They were my QT 40g breeder ~6 weeks while I got the tank setup (no medication).

I just moved them back into the main display last Wednesday. Didn't start seeing these symptoms until yesterday.

Today she took a single bite of mysis and that's all. She's swimming better though. Haven't seen any aggression yet, but planned on spending some time watching from afar this afternoon.

O.K., I don’t think then that the physical move was the cause, I just wanted to rule that in or out.

How is this little guy doing?

Swimming better and less twitchy, but hasn’t eaten since yesterday AM. Trying some other food varieties here in a bit

Also havent noticed any aggression since I’ve been watching from afar.

Quick Update:

She seems to be doing better - I tried some Spirulina Brine and she finally started eating. She's still isolating herself and swimming funny from time to time, but generally looking better.

Still haven't seen aggression and I watched the tank from afar a good bit over the weekend.

My 10+ year old yellow tang is struggling after a move.

All other fish made the move and are doing fine (2 clowns, blue tang, gem tang, 3 anthias, engineer goby, cardinal)

She is generally swimming where the flow is the most mild, and I have the flow very mild compared to our last home. She will eat a piece or two of frozen mysis each feeding and then just chill. She used to eat enthusiastically.

Beyond the eating, what concerns me the most is that she will essentially swim in place and then have these sudden spasms out of nowhere. No fish will be around her. She'll just throw up her fins and act as if she is going to do something and then resume swimming mildly in current.

Any ideas?

How is her bladder did she get hit by one of the other tangs?

I don't know how to check that - what should I be looking for?

Quick Update:

She seems to be doing fine now, but overall less vibrant than before the move.

No more twitching or poor swimming, but she tends to just chill in the lower flow side of the tank for most of the day.

Is being an ‘old’ fish a thing?

I noticed she won’t eat mysis or nori, only spiralina. That certainly wasn’t the case previously.
