Lethargic Angel

[Minch]

My angel seems to have started not eating i also noticed a white mark on its head i think this may be caused by my kissing gourami which always seems to be at the angel I`ve treated my tank a 240 juwell with melafix the tank is well established the parameters have been the same for over a year now.Does anyone know what could be a matter i`ve had the angel over 2 years now and obviously i don`t want to lose it the angel seems to now be a target for my mollies which have also started to peck at it?

Might be a sign of a disease or infection, I know my kissing gouramis and angels started pecking at my opalines when it started getting septicemia....at first I thought it was Flukes because thats a major sign of it but thank god it turned out to be bacterial other than parasitic. Just wait a little bit and I know someone with more experiance will be along soon enough to help you out!! You might want to get you water readings ready tho because thats the main thing considered...Ammonia, PH, Nitrites, and ofcourse Nitrates. Should get your tank size, Temp.,tank-mates...etc. GOOD LUCK

Water stats in ammonia, nitrite, nitrate, and ph.
How many fish and which type.

I fish will get sick if it's stressed by being picked on.

The white mark on the head does it look like bleaching beneath the skin, or like fluffy cotton wool.
Any redness to the white patch on the head.
Any pimples or pitting in the head region.

I would isolate the sick, stressed fish.
