Sailfin Tang Coloring Issue

[brianbrainstein]

The tang is acting fine, but the coloration of his fin at the top seems a bit off. Is anything wrong with him/her or is this normal

Okay, there has been a little bit of fin loss at the top at this point.
Feeding: I have an auto feeder that is mixed with veggie and meaty pellets which was running twice per day. I would hang some nori on a clip every 3-4 days and fed frozen about every other day. Since I've noticed the fin loss I've started feeding nori almost every day.

Is there anything other than diet that this could be?



Tankmates are:
Red Shoulder Fairy Wrasse
Foxface
Blue Throat Trigger
Oc. Clown

I haven't seen any aggression and the damage doesn't look like a bite mark.

Comments are appreciated.

It still looks about the same. Any thoughts?

It looks as if he may have torn it on the rock work or something else in your setup. I have a large yellow tang that's tore his dorsal fin once. But it healed up perfect. I know with most tangs that dorsal fin is thin and easily damaged. I would just keep a close eye on it and make sure its healing up before I would do any treatment. Good luck

Thank you. He does like to dart around from time to time. I'll keep an eye on it.

So the tang has slowly gotten worse. I've tried to catch this guy before but I just cannot no matter what I try. Any idea what is wrong with him?

Some other info:
Other info: he still acts very healthy, zooming about and eating all of the time. I have not notices any fish being aggressive towards him.

My guess would be fin rot ( bacterial) or fin erosion (due to HLLE).

I would pull him and treat with kanaplex. He is visually getting worse. If you are unable to catch him, make sure he is getting plenty of greens and possibly vitamin enrich his food.

I feed quite a bit of nori and have various veggie pellets. I just ordered some Selcon-I'll try using that.

If I can catch him I'll put him through a round of antibiotics
