Yah, started to swim around the tank more. The angelfish would peck on my rocks and sand. Looks like it's eating. I tried feeding it, but my other fish would eat everything before the angel gets the chance to look at it.
Not a good sign!! It could have a internal parisite, What is the salinity at? It could also be that the tank is still to new for those type fish and has not regained a sustainable amount of certain bacterias etc. Can you take a pic?
It depends on if it is dropsy or if it has progresed beyond repair, If you feel that you have the right diagnoses then you should treat the fish, not sure the chemicals that in your area but you should try to treat.
