Hi all,
My juvenile yellow tang has what appears to be a red sore at the base of his left pectoral fin. I’ve only had him for a month. He came quarantined from Dr Reefs Quarantined Fish and arrived on January 5th. He’s approximately 2.5” in length.
Aquarium Info:
Currently fish only
Waterbox 110.4 (80 gal display, 30 gal sump)
87 gallons total water volume
Radion XR15 lighting
This is a new tank. Started 12/23. Dry rock, live sand, bottled bacteria.
Water Quality:
Temp: 78F
pH: 8.0-8.1 (Milwaukee MC122)
Alkalinity: 8.0dKH (Hanna)
SG: 1.025 (refractometer calibrated weekly)
Ammonia: 0 (Red Sea and API)
Nitrite: 0 (Red Sea and API)
Nitrate: 10 (Hanna)
Phosphate: .07-.10ppm (Hanna Phosphate ULR)
Copper: Haven’t tested but have Hanna on hand
Other Info:
Tank is currently fish only as I’m allowing it to mature a bit before moving the corals over from my older tank.
Other inhabitants: a pair of Ocellaris clowns, Bicolor blenny, Royal Gramma, pair of cleaner shrimp, trochus and nassarius snails.
The clowns, blenny, and royal gramma were quarantined in copper (copper power at 2.5ppm) before being introduced to the current tank. They show no signs of disease.
My tang has a voracious appetite. The fish are fed at least twice daily. Most often I feed frozen spirulina brine and mysis. I also mix in Reef Frenzy, Emerald Entree, TDO Chromaboost pellets, and Reef Nutrition Real Oceans Eggs. The tang and blenny enjoy both green and purple nori an average of 5x per week.
All of the fish get along wonderfully. I’ve spent hours watching them up close and from afar. The only “aggression” I’ve seen was a little bit of open mouth postering from the Royal Gramma toward the Bicolor blenny when they were first introduced to the new tank after quarantine but he paid zero attention to it and they get along well now. No one has ever bullied the tang. Though, he did spend 4-5 days last week angry at his own reflection in the glass. He seems to have moved on from that now, however.
As you can see from the pictures below, the “sore” is at the base of his left pectoral fin. The third picture is of his right side which appears normal. I wish I could say how long it’s been like this but it only really struck me as unusual this evening. The only other pictures/videos I have prior to this evening are from January 27th and he looked completely normal.
Is this a bacterial infection, uronema, or just a wound from him actively pursuing his reflection in the glass for several days?
