So everything appears to be the same. The tang is still getting these spots on the fin. At this point it has to be sand. Any parasite wouldnt follow this on and off same type pattern. My clownfish though is still doing a lot of yawning. Its also spending a lot of time at the cleaner shrimp. Havent seen any flashing which is good. On a side note found out that I have monti eating nudis in my tank. Not really happy about it. I am assuming they have always been there and my fish must have kept the population low. When they were all in QT they got a bit out of hand.
