One of my Golden White Cloud Minnows has just appeared with a black spot between the eyes. It's not tiny spots, just one splotch. The fish looks otherwise healthy.
They've been in a new tank for two weeks and we're successfully coming to the end of the cycling period. There never was any problem with ammonia, just a slightly elevated level of nitrates. All the other fish at this point are doing fine.
Is this something to worry about?
