Ok not sure how to pose this question? I have a yellow mimic tang and two clowfish in a QT tank.
Currently there is no medication in the QT, but I had been treating them for what I'm pretty sure is velvet for the last 12 weeks with CP.
They all looked well after the treatment and three weeks back I converted from Hospital to QT for observation in the same tank. Just running carbon and water change to remove the medication.
Last week I did one feeding with API General Cure soaked with Focus just as a prophylactic treatment since I have them in QT. All the fish ate the food.
Noticed this week that the tang has some brown ring like marks on the body. Also fins were getting torn. Breathing was mostly normal except when eating where it seemed to breath a bit more heavily, but it was eating fine and taking the nori.
I was thinking maybe the treating for velvet was unsuccessful, but I now not sure. I was noticing some aggression from the clownfish towards the tang, and I put it off as due to the cramp living conditions (20 L). So today I decided to rearrange the pipes that I put in for them to hide to see if that would help.
I noticed that even after that the clowfish were pretty agitated and kept giving me a weird look. Something clicked and I started looking around the pipes and found this....
Clownfish fry....
So the clownfish had nested (Never did before) in the QT tank and was probably attacking the tang.
Problem is I'm not totally sure if the marks on the tang are from the aggression or if there is a resurgence of the velvet.
Best pic I could get of the tang....
I'm thinking I need to move the tang out to stop the aggression otherwise the tang is going to be in trouble. But I don't have another QT tank that will fit this guy. My other QT is a 10g
Wondering if I should put him back into the DT? The marks are in two ring like spots near the center of the body, and towards the back near the defensive spine, and are brownish in color.
Now that I have some context, it does look a bit like bite scrapes...
I don't have enough experience to tell what else it might be? Any opinions would be appreciated?
