Bristol Tang - Stress marks?

[PaulieReef]

I haven’t seen anyone bullying him but these dark marks on his head and cheeks appeared overnight. Or at least this is the first time I’m seeing it.

Eating fine, swimming fine, no tangs chasing him. Picking at rocks. No rapid breathing of gills.

No detection of stress from other tangs.

Did notice some possible intestinal worms as there are strings coming out of some of the tangs after they eat. Starting a 10 day metroplex and focus in their food today.

Ph 7.9
1.025 salinity
No detectable ammonia
Temp 79

That does look like stress marks - are they roughly symetrical on both sides of the fish?

Regarding your text:

Don't do that! That is too long of a treatment, and unless you calculate the dose properly you will over or under dose the fish. Metro needs to be dosed at around 0.5% to 1% in food by weight. It is very bitter though, so at 1%, many fish will try it once and then avoid it from then on.

Here is my article on proper medicated foods:

I usually recommend to Just use Prazi Pro instead if in the display. Metro or General Cure in a QT is okay.

Edit: The metro with focus is a Humblefish thing.
