Lipstick Tang with dorsal fin always erect
Hi guys,
about one week ago I have inserted a Lipstick Tang (Naso Elegans) in my reef tank (105 Gal). There were already a Paracanthurus Hepatus and a Zebrasoma Xanthurum. After some days of adaptation also with a rigid net in the middle of the tank, it is now three days that it hold ALWAYS (day and night) the dorsal fin erect. It looks like it is blocked and the fish is not able to relax it down.
Have you ever experienced or heard something like that?
Thanks.
