i am having problems w/ an aro...
the aro has been loosing slime recently in small amounts near the head and front of the fish,
there was small cotton growth on the top scales

it went away with a water change and Melafix
then the next day there was a white patch on the face below the eye and above the mouth

i am getting real nervous and am thinking of purchasing medicine IF the problem continues or gets worse (anti-fungal/ malachite green, arciflavine) but i dont know what the true cause is. I dont like putting meds in if its not needed or the problem remains unknown

the water is changed twice a week along with one of the two filters. feeding was reduced. now i only feed 1 cricket in two days.
normal diet of cricket and sw, ocasional pellet

i tried to take pix of the original problem but couldn't get a good shot, ill try again today to see if the New cotton can be photographed

i am not an expert so any suggestions or comments would be great,
pls help
