Hey everyone. What is this white spot near 1 of my bimaculats anthias dorsal fin? It looks like lympho. All three bimaculatus were purchased from reputable QT dealer and have been in tank going on 3 weeks. The other 2 bimaculatus, or other fish, show no signs of loss of appetite, change in personality, etc. My orange shoulder tang had a similar white spot on its tail for a few days when I first got her, but disappeared on its own. I feed 3 times a day, with selcon soaked feedings for 2 of those 3. Is this harmless? I have some metroplex on standby, should I start giving them a treat soaked with it?
Thanks in advance!
