Disease or injury from Tank move?

[Saltine]

Just noticed this on my yellow tang today. Just on one eye, upgraded to larger tank a week ago, not sure if it's stress or something happened in the move. Whitish spot it seems. Thoughts?

Not sure about the spot, but your YT has a pretty bad case of HLLE. Also, a 36 gallon tank is way too small for any species of tang.

Ya it's not in a 36g anymore. Every tang I've seen in an LFS had HLLE how does one treat that?

Thanks

There's no cure per se, unfortunately. Just palliative care - good diet and water quality. Activated carbon has been cited as a primary cause for HLLE, so if you are running it you may want to consider discontinuing its use.

Thanks that's what I thought. I did throw carbon in for a couple days right after the move to make sure anything that got stirred up got absorbed. It was looking better until I add the carbon. It was pulled a few days ago tho.

Thanks

Not all activated carbon is the same. The cheap stuff made from coconut and palm trees is the worst. High quality pellets are far less of concern, but even those should be excessively rinsed and placed in such a way in a filter that no movement and abrasion of the pellets can occur.

Another cause of HLLE is malnourishment. All tangs need plenty of algae, ideally fresh. Red algae are preferred. Unseasoned sushi nori is a good substitute for red algae.

I've been doing nori, but need to get some more. I really think he's just ticked about the move, when I moved him from the holding tub which he was only in for about 30 minutes, he was hauling *** around hitting the walls. I didn't notice anything until today though. I think my carbon was from Wal-Mart, didn't know they were different. Don't plan on running it anymore though.
