Hello. I recently added four new baby clowns into my tank , a serpent star fish and some additional hermits last week. Suddenly my a few of the clowns have looked sick with torn fins. One clown had faded color towards his back of his body and died today
I also lost my coral banded shrimp. Before this new addition my tank was doing amazing and has been well established for over three years. I don't know what is wrong and I am scared of losing more fish. Any suggestions ? I checked all the levels in my tank and all levels are great.
