Hi fish people, does anyone have an answer to fin nipping. My beautiful Black Moor Luther has lovely floaty fins which are way to tempting to one of his tank mates, a smaller red cap fancy goldfish Flash. Flash is now in segregation in a small tank but every time i try and re introduce him to the big tank within a day hes nipping again! Any ideas people, my tank is 110 Litres and has 3 fancies, thank you
