Need HELP!! I have a Fluval EVO 13.5 gallon and it's already established..have it for 5 months now. All parameters are nice and healthy. I have a bubble tip anemone and 4 different corals that are doing just fine. Had a guy from local fish store recently come to my house and tested my water and even brought me a Yellowtail blue damselfish and he acclimated the fish himself. Damselfish died within 4 hours.
This is the 4th attempt in trying to add some fish to my tank and all have died. First time around was 2 clownfish and second time was 2 green chromis.
