Please does anyone have any advice. i got a anenome for my tank and it did not do well so i returned it to the shop. Consequently my fish got white spot, was told to treat them with an oxygen treatment but my orchid dotty back died , then my flame angel died , got more advice from shop and am now treating them with Cuprazin, but my Royal Gramma has died this morning. i had to return my shrimps and snails back to the shop and its all been a nightmare and very sad. i am left with two clowns and i yellow tang and one wrasse. Water tests all perfect. Anyone have any advice??
