Thought I had better update on my Blue HM girly.
Ive been speaking with my LFS owner, who has bred, kept and owned many species of fish for more then a decade and whom I trust totally.
I was treating with Tetracycline, IAL, Aq Salt and daily 75% water changes.
As I said before I spoke to my LFS and told him about Yan's idea and he suggested I use Betadine (not the ointment), and has told me how he has used it many times on his fish for bacterial infections.
He also has a link here on QLDAF which describes how to do it- http://www.qldaf.com/forums/help-fish-health-diseases-water-quality-12/how-use-betadine-fish-pics-47330/
This has helped- whereas the infection/melt/growth has stopped but hasnt gone one or the other, and so he suggested to stop the Tetracycline and continue to treat with betadine. So its moreso just wait and see which way it decides to go.
Im stuck as to what to do, and where to go next..
I uploaded a recent video- I know its not the best very sorry, all I have is my phone- but it just kind of shows how the dorsal has clumped together and grown into the body at the front, leaving the end & back part still normal. The different color in the scales is apart of the infection as well... :/
