One of my smaller brooks was having some issues staying upright in the pond so I scooped it out and salvaged it. Not a mark on it. Once in a long while I get this but no idea why. Less than 1 percent of the fish so I don't lose any sleep over it.
Anyway, just thought I'd share this picture. Fish was getting there with the extended lower jaw but the spawning colors are just starting to appear. Some of my other brooks are quite red orange on the flanks already.
