sandy like white spot

I have recently set up a tank. Purchased a strawberry pseudo. to begin cycle. Live rock doing extremly well, some coral. Noticed a granular spec on top fin of fish. Very active fish. Should I be alarmed? Thanks---Bob DeRiggi

You should always be alarmed when you don't quarantine new fish before introducing it to your display. Fish do carry parasites from the wild, and it is always a very good idea to take care of the parasites before introducing the fish [with its parasites] to your tank.
Also, it is really not necessary or a good idea to place a fish in a cycling a tank. A new tank will cycle very well with LR.
Is this just a single parasite? Or are you seeing more by now? You really can't treat parasites in a display tank.
