Bartlett Anthia Acting Weird

[Marco S]

I have several Bartlett Anthia's in QT currently and three are in a 10 gallon QT with a Clownfish. They all have been through 2 weeks of CopperPower and three API GC treatments while feeding MetroPlex. After they were done with copper I transferred them into this 10 gallon to continue treatment and shortly after I noticed one had fin rot and lost a majority of its tail. Shortly after the loss of the tail, it started hanging out in the corner with either its head straight up or straight down and stopped eating for a bit. I did not want to add anymore medication until after the CG treatments so I just watched it and its tail eventually started to grow back. It is looking fine now besides the weird behavior and it stays this way most of the day. It does eat,but not nearly as much as the others and it can swim normally when it tries to eat or when another fish comes over and tries to interact with it.

I am posting a video of this behavior and would like any advice on what to do. I was going to treat for fin rot, but the tail seems to be growing back fine on its own and I do not want to add any unnecessary meds at this point. Just an FYI, there are no visible marks on this fish. What look like marks on the video are on the glass, not the fish. I just got through with QT and need to do a water change and clean the glass...



Any help would be greatly appreciated! @Humblefish @HotRocks @4FordFamily

Is there any aggression between the anthias?

Certainly odd behavior. Do you have any eggcrate you can drop in to separate a small sectionof the tank for the fish?

There was a bit of aggression in the copper tank, and it settled down to a nip or two here and there, but they all partook in it and this is the only one acting like this.

As far as the eggcrate, I can do better and put the other fish in a holding tank while I finish the last two weeks of observation and leave this one alone for now. I have two other Anthias in another QT that still need to go through copper and I want to put them in my DT all at once so I have time to separate them for now.

See if that allows a change in behavior. Have you treated them with metro at all externally or internally?

They are very uronema prone. When you move him to his own tank you can feed food soaked with metro as well as dose the water in case he’s dealing with uronema.

I have been feeding MetroPlex to all of them for about three weeks now. One of the other batch of Anthias and a clownfish did die of Uronema so it is most likely in the tank now, but it killed the others very quickly and these all survived with no signs of infection...just this one with weird behavior.

Edit: To clarify a bit, the other Clownfish of the batch in the video died of Uronema while in copper and I since transfered them out of that tank and sanitized it with bleach for 24 hours so this tank should not have Uronems. The other batch of Anthias and one Clownfish had Uronema while dosing API CG and one Anthia died of it and I started dosing Metroplex as well as CG and they are all doing good, but most likely that tank has Uronema in it, not the one in the video.
