Is Henry sick?

I have 3 clown loaches and one has seemed to start turning black all over and now the second one is too! What's wrong with them?

Could you please give us a bit more info. if possible, such as:

How big is the tank?
How long has the tank been established? Is it cycling/have you cycled the tank?
How many fish in it?
What are your ammonia, nitrite and nitrate levels? PH level?
Tank Temperature?
What are you feeding?

This info. helps narrow the field for us! :ssmile:

Can you get us a picture of the blacked-out loaches??
