Fish reappears in Pond after month absence.
I have a approximately 2000 gallon pond with mostly open space but one ledge where the fish can be out of sight. This fellow was out in the spring and did some eating for a week or two, but then disappeared for the last month plus. His fins look like he’s been through the war. Any thoughts on what might cause this behavior? I’m guessing he was sick and was recuperating but any thoughts would be appreciated.
