Advice on HLLE

[George]

That's a beautiful blue face you have there. I am an angel nut myself so I am glad some one likes angel fish as much as I do.
Apparently you have done you research and as you said in your post no smoking gun has been found for HLLE.
I just wanted to throw out 2 suggestions here:
1. Diet. Sponges and tunicates are their primary diets in the wild. The only food that has sponges as the ingredient is ON angel formula. Unfortunately it's not available in Canada. You probably have to bring it from the states by yourself somehow. I also read a lot about angelixir and concluded that it's another snake oil.
2. Environment. From my reading of all HLLE stories. Sometime it could be cured by switching tanks. See if you have another tank or someone else's tank to host the angel for some time. Not sure what's in the original tanks that caused the HLLE.
Good luck and keep us posted.
