In the last week, we have lost most of the fish in our tank. We had, three clowns (two snowflake and one white that we’ve had a hard time identifying), a coral beauty angelfish, a saddle Valentino puffer, and an orange dot goby. We do have a few snails, 2 camel shrimp, 2 peppermint shrimp and some hermit crabs. The coral beauty was the last fish we added about one month ago. The other day we added a pistol shrimp that instantly paired with our goby. The morning after we added the shrimp, our coral beauty was dead. She had no symptoms/irregular behavior. The same day, our clowns looked like they had Brook and we FW dipped. The next morning, one snowflake clown was dead. The morning after that, the other snowflake was dead. Now my beloved white clown is staying towards the bottom in the same area all day and won’t eat. Which is entirely not like Tippy. Our puffer and goby do not seem to be infected. Does anyone have any ideas? Thanks in advance!
