Hi everyone! I recently just bought a Baby Powder Blue Tang (1.5-2in) (Quarantined) in copper and praziquantel pro for two weeks before being transferred to a clean system for observation from my Local Reef Store. I added him today and drip acclimated as usual. I noticed that he had a single spot on his fins, there are no other spots on him as far as I can see. I don't think it's Ich but it does remind me of velvet many years ago. But I don't really know what it is. It could be Lymph but I'm not quite sure. It's not my first powder tang as I kept one many years ago back in 2017 before rehoming it.

Notes:

Tank Age: 7 years Old

New Additions: Clean Chaeto, Banggai Cardinal, Xenia Coral (Quarantined as well)

Other Inhabitants Blue Tang, Foxface, yellow tang, pair of clownfish, flame angel, sleepyhead goby.

Salinity: 1.025
Phosphate: 0.1
Nitrate: 11
Ammonia: Undetectable

Symptoms for any of my fish (including the Powder Blue)

Scratching/Flashing: No

Swimming in Powerhead: No

White Spots on Other Tangs: No

Twitching: No

Heavy Breathing: Not that I can see anything out of the ordinary

Other: I am currently quarantining inverts right now, but I do my best to avoid cross contamination.

I do not see this as parasitical but rather a grain of sand from sandbed. lympho which I am not sold on or a fin ray spot. Sand is my suspect. Keep an eye on it for any additional, enlargement as examples.

If it was sand, surely it would have fallen off by now, no?
Sometimes not as the fish have a slime coat. Other as mentioned would be Lympho but unusual for one single dot. Fin ray dot next possible

Is Fin Ray Dot basically an injured fin?
Its the structure of the fin made of hard and soft cartilage. Often a slight imperfection will appear as ich, lukes and bacterial in which it is not

What you need to do is observe this spot for a few days…if it stays in place, it isn’t ich and is likely a broken fin ray. If it goes away, it’s likely a dust spot. If it goes away but returns in different locations and in different numbers, that is more likely ich.

Would there typically be symptoms like aggressive flashing, if my PBT had ich? At least in my experience, any new tang I added into a observation/Qt tank would flash/scratch within hours because of ich due to stress (particularly for blue hippo tangs).

PBT will generally breakout with a series of bumps
Flash and scratch is associated with flukes over ich

So assuming he hasn’t shown any bumps over the next few days (like till Sunday), it most likely means he doesn’t have ich, right? At least in theory, the stress from being in put into a new environment should lead him to show ich after 24+ hours.

I guess I’ll have to wait for a few days to see. It’s going to be dreadful for me if it is ich. I managed to keep my DT clear for 7 years. But oh well..

Flashing/scratching is more of a sign of flukes, not so much ich. Sometimes, when ich first gets started, the fish may scratch, but that usually stops when the infection gets ramped up.

have you done a quarantine with this fish? If not, go at least 14 days of assurance that there is no disease which can be triggered by skin irritations and water quality

Indeed, the fish was quarantined for 14 days in cupramine and treated with prazi pro for flukes and then moved into observation before it made into my display. So far he has no bumps right now. But I will update in a few days if something looks abnormal.
