Came back from work, one of the WCMM is in a state, clearly dying. Removed it and dispatched it. Any ideas what's happened? No other fish showing any signs of distress. It was 18 months in the tank. Cause for concern or just one of them things?
Hi, a little while ago, one of my little Ember Tetras seemed rather unwell. It had turned blue!
Next day, he was fine. All were accounted for, so he hadn't snuffed it. Any suggestions as to what he might have been suffering from?
