For 3 weeks my fish flash/scratch on the ornaments/subtrate/plants.
I was recommended to do daily water changes of 20%. It seems to get worse with water changes and then calms down a bit but still scratching but less often. I went to pets at home. they told me to add live plants,so i have done, but said its a mystery. Been to local aquarium place. They seem to think its because my ammonia has raised to 0.25 and nitrates to 5.0. No matter how many water changes i do, the levels dont drop.
My readings are: ammonia 0.25
nitrite 0 (it had spiked to a dark purple colour on chart - forget which
level but has now dropped)
My tank is 10 gallons. It has been set up just over 6 months. Tank cycled when set it up. Ammonia and other levels were all reading 0 until a week after fish started scratching.
How do i sort this problem. People have suggested it could be flukes or parasites but i dont want to just dump chemicals into tank and do more harm than good.
Had white spot in tank but that has all cleared up. Been clear for around 3 months. all fish are eating well and there are no signs of illness or spots or marks on them.
My local shop have given me some stuff to put into tank to lower ammonia, which was yesterday, have said wait a week... no feeding fish..... and test tank levels again.
I have not lost any fish yet since scratching began.
Local shop also told me im doing too many water changes. They have told me to only do one water change a month. I've always been advised with small tanks like mine, 10 gallons, small water change of 10% every week was healthy for the fish. and i've only ever vacuumed the gravel once every 2 to 3 weeks, as not to stress the fish too much.
I am at a loss of what to do. Any help or suggestions would be very much apprechiated.
