Washed out fish

[brokly]

Our two black moor fish are looking progressively less black - they're starting to look grey with hints of gold here and there. Otherwise they seem well. Is there anything we can do to restore them to their former colour? (They're fed on the usual fish food sticks plus the odd pinch of freeze-dried bloodworm.)

Some fish benefit from adding salt to the tank. ask at your fish supplier for the proper salt and if it is suitable. It improved the condition of most of my fish and enhanced their colours.
