Angel Not Eating

[S Herbert]

Hi,
I have an Angel fish that is not eating. He doesnt eat anything and is painfully thin now. Its been just over a month and i have not seen him eat anything. He is not interested in the food put in the tank at all.
He is in a 240L tank with 3 other angels 4 keyholes and a pleco. The water temp is 28 the pH is 7.5-8 and all other conditions are within normal range. All other fish are fine and eating well. I have tried treatment for internal parasites, a general tonic, and a treatment for worms. I just cant figure out what is wrong with him.
Any help/ideas much appreciated.
Thanks!

What do you usually feed your fish?

Tetramin Flake Food and Tetra Prima Granule Food
I've tried coaxing him with bloodworm too.
Oh, and the plecos have algae wafers

The ph is very high for an angel set up - they prefer acidic water. I dont think that'll be the cause of the problem, but it's worth knowing

I had one very skinny angel out of my gang, and he didn't grow at all for 6 months - his "brother" is my biggest angel and dwarfed him, since removing his brother to another tank, he's now taken over as boss - found a mate, and started growing. Dont suppose he's being bullied at all?

Which specific meds did you use? This sounds like an internal parasite problem, a month without eating is pretty severe for a healthy fish, real rough on a sick one.

Though an old topic but it maybe worth concluding.

Iv had a similar problem with one of mine who died after, but didnt last a month with no food, this was a a space of a few days....I wonder why a month?
