Nikki Firstly welcome to the forum. It is clear that you recognise that your current fish are not ideal tank mates and your are in the process of rectifying the situation. You are to be commended in do so. The test readings that you have done don't indicate anything out of the ordinary but when did you do the tests. If it was after the water change it will have an immediate impact on the results. Can you provide a bit more information i.e the type of filtration including turn over, feeding regime, gravel cleaning regime. I suspect that it has more to do with the water chemistry rather than a bullying issue.
