ill suggest that you let others adopt your 4 anemones and other corals... even if without checking your water parameters, it is so obvious that your water parameters is way out the normal...
after your tank becomes a fowlr... then you can start giving your fishes some treatment...
anemones are hard to keep... it requires high lighting and mature tank to survive... anemones are not like fishes... they split para dumami... and most of the time, they didnt reach that stage because they are caught in the wild immediately...
