What is wrong with my Tang?

[A.Terry867]

We have had our tank up and running for a month now, we have not had any big issues since. This powdered blue tang has been in since the tank began. Recently we brought home a small blue hippo tang, and found it dead with no spots or anything. Now our blue powdered tang looks like this… how do I treat? And do I treat the whole tank directly since there are other fish in the tank as well?

The fish medics can help with the treatment part. However the big issue I see is a powder blue tang in a new tank as the first fish and then adding another tang. PBTs are nasty and should be the last fish added. What I think probably happened is either the hippo brought something in the tank or the PBT killed the hippo and stressed itself out and now has ich or whatever it is.

How big is your tank?

Thanks forgot to add that to my post!

Looks like ich to me, but the fishmedics can confirm.

Also, when you say the powder blue has been in there since the beginning, do you mean since the set up, or since the end of the cycle?

And also piggybacking on the size of the tank.

I think you are rushing things too much

Another vote for ich.
Ideall treatment will be copper (coppersafe or copper power) at 2.25 ppm in a quarantine tank for 30 days, leaving the display tank fishless for 60 days.
If there’s no inverts in the dt, hyposalinity is an option.

Yes - that’s a moderately severe case of ich, you’ll need to treat all exposed fish asap. Coppersafe in a rock/sand free tank is best, but hyposalinity also works. Neither of these can be done when invertebrates are present.

I wish there was more info out there about power blues and them being nasty.

I wish there was more info out there about power blues and them being nasty.

Yeah - they can be really mean and are also “ich magnets”. I stopped getting them for close to 20 years because of the latter issue until I started using coppersafe as a preventative.
