Black Spots On Tetra's? Disease?

[TDPUK]

Hello.
 
I'm not sure if this is an actual emergency or not but I don't want to chance it. Does my tetra have some sort of disease? I've noticed another one of the orange tetras also has this. 
 
I awoke to find my polka dot botia dead at the bottom of the tank ( He had been missing for a few days )
 

 
Thank you!

What type of tetra is it?

Think it's a minnow. Never seen this, but looks a bit like a parasite like Ich / Velvet to me ???

Its a white cloud mountain minnow, could be black ich/black spot which is a parasitic similar to ich (genus Paravortex) Esha Exit has this disease on its list of things it cures, mostly it will go away on its own, but that looks quite a heavy infestation personally I would be inclined to treat it. Esha exit is safe for delicate fish and snails so no need to remove them. Hope this helps

Don't wait to long with treatment, cause most of these parasites infect gills after some time.

Thanks for the replies, is Esha exit safe to use with my other fish? I don't want these tetras to wipe out all of my tank.

Yup, it's fine for everything.  I had to use it in the past and even the catfish were fine.
 
Just don't overdose it.

Yup again. If it is such a parasite you'll always have to treat the whole tank / all fish. Though not visible it is in your whole tank.
As said : I never saw black Ich / black spot before.
