Thanks for that. I'll leave it then and keep a check on water chemistry
before introducing more fish.

Hello,

I have just lost white cloud mountain minnows to fin rot. I am guessing
that this is because the tank had not been fully cycled. Now I am more
clued up on the cycle, etc, what would be the recommmended course of
action
to take? - take everything out, wash it and start the cycle again, or
leave
the water in there that the minnows were in and keep an eye on water
chemistry until it completes the cycle?

Leave it in there. The organisms that cause disease are there all the
time, you could disinfect the entire tank but that would mean starting
the cycle from scratch. Fish get sick when they are unable to to resist
disease, often due to bad water conditions or other stress. Since you
were using the minnows to cycle the tank then high nitrite levels are
the likely culprits. So the solution is to continue to cycle the tank.
Reality can be harsh.
