Neon Tetra Trouble Again

[aquababy]

I have had lot of fish troubles but everything turned out alright. I recently bought a 65litre tank and transfered all my fish from their 27litre tank to the new one. This was last monday. Since then things havent been too bad. I wasnt sure if my fish had whitespot or were just stressed from the move so I started treating them with WS3. The treatment is for 2 weeks and this the last week. The problem is one of my tetras was behaving differently. He moves his mouth all the time as if he is eating (not gasping for air). His eyes look a little large and round kind of protruding from his face and today i noticed a faint haze of soft white over the top of his back. I have some pimafix which is for popeye and bodyfungus but don't know if that is what he has . I don't want to treat him with the wrong meds. I don't know if I can use any other treatment whilst using the whitespot (WS3) treatment.
The tetra is eating and swimming ok but sometimes just abandons his friends and swims alone in a corner.

Ammonia is at 0, Nitrite is at 0.1 and nitrate is at 5.

I have 2 bronze corys, 3 panda corys, 2 habrosus, 2 minows, 2 rummynose and 4 neon tetras (including the sick looking one)

The tank is 65 litres which is about 14 gallons I think. I have two filters running and an airstone thats connected to an airpump.

I feed my fish once a day and do a water change once a week.

Please let me know if theres anything else you need to know so I can get an early diagnosis. I would also like to know if I can mix the pimafix with the WS3 ?

Whitespot looks like the fish has been sprinkled in salt.
Or spots the size of a grain of salt.
If the fish eyes are bulging out its popeye.
Also the white patch on the back of the fish does it go down the sides of the fish to form a saddle shape.
Does it look fluffy in appearance or just bleached out beneath the skin.
Any signs of flicking and rubbing.

Hi Wilder.
Im sure its not white spot as none of the fish have any tiny white specks on them now but one fish did have when i moved them to this tank. There is only one tetra with a white spot on his back now which sticks out. He has had it when i transfered him from the other tank but he didn't have it when he was in the previous tank. He is eating and swimming and looks ok and he is behaving ok. The WS3 treatment doesn't seem to have affected the spot on his back which is larger than normal whitespots.
As for the tetra with the bulging eyes, the white patch runs down his back only and it isnt fluffy. It looks more bleached but under the skin and its not a bright white but a soft ,faint white. Hes not flicking or rubbing against anything, just opening and closing his mouth as if hes eating.

Its sounds like columnaris to me if its bleaching beneth the skin.
Uk myxazin and pimafix.
The spots could be a columnaris spot it will be a greyish white with a circling of red on the edges, or a red centre.
How does his red stripe look is it still vibrant red.
