has anyone treat gill curl without surgery? I'm doing water change every three day, added salt, and increase temp to 84. It looks fine if swim against current but when its with current it doesn't look good. it's only on one side. I suspect this is due to a hole it got ( don't know how) on the lower part of its gill menbrane. I've been treating it for 2weeks already. If it's not healing after a couple more week then i will do surgery.
