About a month ago I put 3 new tangs (purple,sailfin,qnd powder blue in my waterbox penn 6025. I already had a yellow tang. Well they fought at first. Now they seem better although the yellow tang and purple tang still are kinda fighting.
After the fighting stopped the 3 new fish I think had ich. Like week 2. Week 3 2 of the new tangs seemed to not have it. But the powder blue has something. And now it looks worse.
When I say maybe ich , is because I have seen bad cases of ich and marine velvet before. And while it is small to see I have generally seen it just looking at the tank. With these new tangs I can only tell if I’m right on the glass searching for it. All the fish are eating with the powder blue eating more each day but the least amount of the 3. I have a uv running as well. Idk if its tinfoil, just slowing it down so they suffer more , or actually helping. But the first day I thought I saw spots I thought if I don’t plug it in then I didn’t do everything I could.
So now I am at a point where I’m not sure what to do or if it’s ich. The powder blue is the only fish kinda acting strange , looking kinda white, def has something on the skin but is eating and kinda seeming ok.
Do I leave it be
Do I take out the powder blue and do a safety stop dip.
I have a 20 gal I can use for short term quarantine but not really interested in doing that.
Just take him out …
I know this pic doesn’t help. Or atleast I can’t see what I am seeing in the photo.
Thanks for any help,
