Hi I am new to fish keeping I have a tank for my grand children with 2 fantails in it. I have a filter and an aeration system. they have been happy and healthy for well over 3 months now (the fish that is )
I addition to normal flaked fish food I feed the fish bloodworm twice a week as i was advised when i bought the fish. i usually feed the bloodworm from the packets (tetra range) but early this week i gave them fresh bloodworm and some fresh daphnia from another pet store as i thought they would enjoy chasing their food. Since I fed that to them the silver fantail has been gradually turning black from the tip of its head backwards have i done something wrong?
I dont want to harm them in any way so any help will be much appreciated
