Strange Angelfish behavior

The source of the parasite may have been the fbw I a few years back started feeding only hakari fbw as they are the only ones that are sterilized they call it bio pure and I have not had a parasite problem since.

2 things that should always be done when a fish is not quite right is PWC as much as 50% a day or more and bump up the temp 2-4 degrees. These 2 things stimulate their metabolism which helps them fight what ever is wrong.
 
Draal5: I have only ever fed Hikari brand frozen bloodworms, that's what my LFS carries.

Update:

After dosing with the Prazipro last week I saw only a slight improvement, the angel still wasn't eating but was a little more active. I also purchased a heater, and the tank is now at 78F.

I dosed with Prazipro for a second time today (following label instructions and the recommendation of my LFS), and offered fbw a few hours later. The angelfish was really interested, and even ate one! Didn't even spit it out :) I only saw him eat one though, so I'm hoping his appetite continues to improve.

I can't seem to catch a break though, while I was feeding the fbw I noticed that my neons seem to have erupted with ich overnight! I have some Ich Clear fizzy tabs (main ingredient victoria green), can I use these with the Prazipro (main ingredient [FONT=Verdana, Arial, Helvetica]praziquantel) safely? I am going to create a new thread in the general freshwater for this as well, since it is a little outside cichlid territory now. I will update again if I see any significant change in my angelfish.

Thanks for all the help so far you guys :)
