SICK Fish Please HELP

[Holly w.]

I got a fish from my lfs, about 2 month ago, was told its an anthias but not to sure seeming how I got a coral beauty angel from there and they told me it was a goby... my win!! The "anthias " is usually very active and food aggressive. The past 2 days it just lays on the bottom of the tank and is barely eating. I checked all my levels everything is good. Tank mates are a choc. Chip starfish, snowflake eel, lunar wrasse, and few hermit crabs. 120 gallon cycled aquarium, the red at the base of his tail fin is algea on the glass

imo this looks like a bloched/borbonius anthias.
Pretty expensive usually..

as of what I know they like a bit colder water..
