Emporir tetra unwell

[Sbradley81]

Hi,

I have already lost one emperor tetra this week, and now another looks very ill. This morning it had a white cyst like thing on its side, and now it has gone leaving a nasty wound.
I have a feeling it is ich related, but not sure.
He is very swollen and not eating. I think it's too late for him, but don't want others getting ill!
Pictures of fish attached.

I don't see any signs of ich to be honest. The red streaks that can be seen in the pictures could be do to ammonia poisoning or a bacterial infection. Do you know the current water parameters such as ammonia, nitrite, and nitrate as this will help rule one of them out?
