Ruling Out Some White Dot Issues

[bevo5]

Hi all - I've got a little blue tang in my QT and of course he's got some issues because he's a blue tang.

The fish had clear flukes about two weeks ago. After a fresh water dip I did a round of prazi.

I was also already treating copper power because the blue tang had some ich spots. I know it's not ideal to double up, but I added more O2 and just bit the bullet.

They've been at 2.0 copper power for 18 days.

Last weekend I noticed some chunky spots on the blue tang. Bigger than ich. I figured more flukes hatched so another round of FW dips and another round of prazi.

Now I'm seeing more bigger spots - more the size of those little Spirorbidae type things that grow on walls. All on one side - which is maybe the side he leans on when he hides. Maybe sand?

Should I: do another round of FW dips and prazi?

Seems like ich would be dead after all this copper?

Is there another med I should try?

He eats like a cow but is definitely still a bit pinched. I wonder if it could be internal?

Anything spring to mind?

PIctures are really hard to get of this guy.

Couple of possible explanations for those spots.

First could be Lymphocystis. Are they raised a bit and cottony, fibrous, or cauliflower like in texture?

The next possibility is that it is a gram positive bacterial infection. It can look a bit like Ich, and sometimes can present with a pyramidal shape often with a very short strand kinda attached.

Both of the above are found during and or after treatment with copper as the fish's immune system is suppressed from the effects of the copper.

Hi - thank you for the info.

I'll look more closely for a strand. I'd say it's not as dramatic as the Lymphocystis.

Should I just treat for bacterial infection or keep the water clean and see what happens? I have a fairly decent selection of meds on hand if there's something you would suggest.
