Is This Normal For A Cory Or Have A Problem

[lilacamy931]

I have 6 habrosus and one recently looks completely different from the rest in colouration, very noticeably so, but I cant remember if he has always been like this or has a illness
here are how all the others look

And here is how he looks

Cant decide if he is on the skinny side or not...He rests more than the others but then always has.
They have weekly water changes, nirtites and ammonia 0, nitrates around 5.

I am on complete panic stations at the moment as with my pygmies there was an epidemic and out of the 13 there are now 3 left (though havent checked their status today..) All other fish seem to not be affected but of course if there is something going on wish to nip in the bud.

Never kept this type of cory so not sure what the colouring should look like.
Does he look pale or darker in colour.
Is he leaning to oneside when resting.
What does it look like when he goes to the toilet.
How do his barbels look. Do they look thin and short.
Does he look pinched in around the tummy area.
He dosn't look that skinny to me.

Corys are very prone to bacterial infections,. So if he's acting listless and lethagic, I would issolate him and try a bacterial med.

I think I will go with a bacterial med on this one thanks Wilder (what is it with my cories). The first picture is their usual colouration certainly not what is in the picture.

He just rests on the bottom cant see onesidedness
Havent seen him use the loo
barbels seem fine and no degradation
I think he looks skinnier compared to the others but only slightly but could be paranoid

I think I will separate him and observe on this one. Thanks so much Wilder as always, what would I do without you!

I love corys fish they have beautiful eyes, there cute.
Let me know how you get on.
Good Luck.
