I have a Foxface (~7") that has developed fin rot in the tail fin. I have tried several times to catch it for a quarantine tank with no luck. I have a 175 gallon reef tank and dismantling it is a big job. So, I left it alone hoping it will get better. Well it is not. Now it is so bad that it has trouble swimming. Here is a photo.

I am wondering if I can still save this fish without getting it into a quarantine tank by using something like Aqua Pro-Cure by Fishvet. Any suggestions?
I also have a second fish which is a yellow tang (~4") that has developed fin rot. Here is a photo.
I think if I don't do something, they are just going to get worse. Here are the particulars of my system:
The Foxface has been in my tank since day 1 which was 3 years ago. It developed fin rot about 6 months ago. The yellow tang was purchased 4 months ago and I noticed fin rot about 3 weeks ago.
Tank mates are a Powder Blue Tang (7"), Sweetlip (7"), Brown Tang (3.5"), Skunk Clown, Royal Dottyback, Green Chromis, Fire Shrimps, Pearl Crab, Star Fish. No one really bothers the Foxface since he is one of the big guys. He was really aggressive before and killed the other Foxface 1 1/2 years ago.
The Yellow Tang is eating fine still, but the Foxface doesn't eat that readily. It tends to hang around near the surface and often more vertically than horizontally.
My water parameters are normal except NO3
is on the high side at 80. I am doing water changes more often to try to bring it down. I have a sulphur denitrator plus a DIY coil denitrator. The media in the sulphur unit has expired and it is putting out more NO3
than in. So I need to replace the media. So far, after 2 months, I still can't get the coil denitrator to output lower NO3
is zero, phosphate zero, ammonia zero, alkalinity 9.8, pH 8.2, temp 78F fluctuating 2-3 degrees daily, SPG 1.022.
The Foxface seems to be less active than before. It does not chase after the food like the others do. It does not hang out in any particular spot in the tank, but near the surface. Also, it tends to hang in one spot rather than swim around. It is not flashing. I have not done any treatment yet except trying to use AZNO3 to lower the nitrate level.
My system has a hybrid filtration system. Under the main tank is the standard filter sock, skimmer, wet/dry bio balls, and a sump with live rocks, sand/mud, and mangrove plants. Water is pumped from the sump to a Hyatt filter system which consists of 2 cartridge filters, one containing tri-based carbon and the other calcium rock. It is then fed back via 7 jets to the main tank. I am still struggling with the flow rate. I think it is only running at around 1200gal/hr. But I have 4 powerheads controlled by a wave maker running 2 on 2 off to increase circulation within the tank.
My main tank is 175 gallons with live rock and 2" sand bed. It is a see through tank with the rocks stacked with a lot of through holes. This makes catching a fish impossible. With all the corals and anemone, dismantling to catch the fish seems impractical. Here is a photo of the tank. It is an older photo before the powerheads were installed.
I dose ESV B-ionic and iodine with an auto drip system. I dose Strontium and Molybdenum manually. I also have been using Joe's Juice to fight with a major Aptasia issue. Other than that, no other medication.
I have been researching medication for fin rot that will work in the main tank of a reef system. Melafix seems to get mixed review. Does anyone have experience with FishVet Inc's Aqua Pro-Cure or Revive? Am I too late with the Foxface without antibiotics? Perhaps I should try one of these at least to cure the yellow tang. You opinions are appreciated.
