Sick Blue Ram

[tropfishmelb]

Hi There,
 
Can someone please tell me what is wrong with my blue ram?
Water parameters are all fine:
0 ammonia, 0 nitrite, minimal nitrate. PH is about 7.
 
I have added an airstone, and temperature is at 27 celcius.
He has been like this for a few days now.
 
The tetras and other blue ram seem to be fine..
 
Thanks for the help.

Looks like internal parasites. Give him some meds and put him in a hospital tank
