Hi,
New reefer here. First post. So, I setup a new tank six weeks ago. Got a couple of clownfish and added them to the tank. It was cycling well. Then I started reading more and realized that I should have quarantined even my first fish before adding them to the DT. So, I decided to setup a QT and let my DT fallow for 76 days even through the clownfish weren't showing any signs of disease.
This weekend I also got a couple green chromis and add them to QT so the two clownfish and the two green chromis will go through quarantine together (I know I probably need more green chromis). Anyways, when I brought the green chromis from LFS, it had normal coloration but then I started noticing a black mark on one side of one of the fish. The other side of the green chromis is fine and the other specimen is also fine. I don't know if this is a disease or something else. I will be treating for all diseases anyway (haven't started adding copper, etc. to the tank yet). So, I wanted to know what it is
I have read that green chromis can get uronema but this doesn't look like it.
Also weird is the fact that it sort of grows and shrinks. Something related to stress? For example, I did a 50% water change because the ammonia was rising and it probably stressed it out and the black coloration spread to more of the body (but still one one side) and then after a while it was back to the original state near the head.
It is eating fine but it is the shiest one. Mostly hangs in one corner or goes in the PVC pipe. There doesn't appear to be any bullying issue.
and here it is soon after a water change. See how the dark coloration has spread (it returned to the original state after a while)
and here is a short video
