hey
My blue hippo tang had it and I healed it.
This was before:
After:
Basically I moved him over to the quarantine tank and I did not use any
carbon. I just used purigen. I do remember that when i first put my hippo tang in my new tank the carbon was just gushing out. Two days later he started showing signs of HLLE.
For his diet I made sure he always has seaweed available. I feed him mostly green, but also
feed him red and brown. Don't feed him nori. I use Ocean Nutrion macro
algae. Make sure that is always available to him.
I also feed him mysis shrimp and this food called herbivore health
made by a company called feeder fish
http://www.calpetfoods.com/. I alternate every day and soak
the food in selcon and vitachem.
I also add beta glucan to his food. I noticed after he started to take it the healing seemed faster.
You should also move him to a new tank where carbon has never been present. Just removing the carbon from your current quarantine will not do the trick.
If you decide to go this route the hippo might get better or the disease will stop getting worse. i was lucky. Also if you heal him and you put him back in you DT he will probally get HLLE again. I ended up giving him away.
Hope this helps.
