Stayed at a hotel down in Port Aransas for a beach trip, and they had a pond out front. The pond was a bit brackish, I think, though I didn't have a hydrometer. I went over to check for some fish, and among the gambusia were a bunch of taller-bodied fry that were pecking at the leaves. Couldn't catch anything big with a fishing pole, so microfishing ensued. 

I didn't manage to catch any of the taller-bodied fish with a line, I had to use my trap as an improvised net. I think they were baby flagfish, which explains why they weren't interested in my bait. I did, however, catch a bunch of gambusia, including this tiny fella. Yes, I know the pics aren't great, but you can see the fish's size, the penny, and the hook/line in his mouth. 

Gambusia caught on a tiny hook baited with a fragment of white rubber. June 9th, 2015. Anyone caught a smaller fish while microfishing?

This naked goby from Ocean Isle, NC is probably the smallest I've caught.

While musky fishing with a friend of mine, he foul hooked a satinfin shiner on an 11" musky lure.  He termed it his "personal least"     On this forum, that's an accomplishment  ...something that I hope to improve on in the future!

Somebody here hooked an Elassoma a few months back ... was it Don?  To me that one takes the prize because they cautiously study prey before they strike, unlike a Gambusia or minnow that will quickly bite at anything.  The satinfin shiner may have been attacking the lure, thinking it was a rival male!

Interesting!  I hadn't thought of that, but it's certainly possible.

I think this Slender Madtom is the smallest I've managed on a hook. I feel like I may have had some young Bluegill that were slightly smaller, but that's just a guess from a fuzzy memory!

That's a really tiny cat! What'd you catch him on? Meat?
