So looks like it's not gonna end well for meI would say ‘Yes,’ provided you have moved it to another tank, and your water quality is very good. Keep us posted.
By the way, yesterday I had to return my H. Singularis to its original tank; I switched him into a tank with an Emperor Angel and a Purple Tang — just like you— and they both kicked him around for two days and I could tell they weren’t going to stop
This was him 2 weeks back when its all started . it recovered from all those injuries and now finsSo sorry! My H. Singularis is the size of my hand, and he had a rough time. But your fish really got chewed up badly— I’d worry about infection setting in, even if he get’s to a new tank.
