Squeeky, how is the rest of the fish population? Can you do some sampling to determine if this fish is unique?

If you are not removing enough to use as forage, expect more of these and possible other problems. I've twice killed everything in 1/4 acre ponds due to neglect resulting in fouled water. However, it should be a little early for you to have a crowding problem.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
