First Fatality

[LeahMay]

Think I may well have hit my first problem, white spot.
Now I've noticed small grain like spots on a few fish probably every 1/5 has one or two spots.
I am best off treating the whole tank or removing the poorly fish?

I would treat the whole tank.

Thought as much, looks like I'm spending lots of money on treatment. Damn you tank of many litres.
