Hi. I received 3 yellow pyramid butterfly fish on Friday afternoon. All three ate within a couple of hours of being in the tank. The tank is a 40 gallon cube with a fully functioning biological filter. Ammonia and nitrite test 0. Salinity is 1.109 that matched the vendors shipping water. All three are eating vigorously and acting normal. However, I see these white spots on all of them maybe 3-4 spots on each. I am not treating and don’t plan to unless I need to. I’m looking for advice on any steps I should take at this point if anything…thinking of doing 1.013 hypo for 35 days in case it’s neo. Any advice would be appreciated!
