I have a female Black Banded Darter, Percina nigrofasciata who searches for food in this position. At first I thought her swim bladder was messed up but she can right herself, swim upright and sit on rocks or the gravel. That's duckweed above her.

Wow if there is nothing wrong with that fish that is one adaptable fish!

I guess that's one way to turn a subterminal mouth into a supraterminal one....

That is what she is doing. I believe she is searching for Gammarus. She is also positoned to grab the first foods that come in the current. When I quit adding food she drops to the bottom to feed with the rest. None of my other Black banded or any other darters have been seen displaying this activity in my fishroom. Just wondering if anyone else had.

That's wild stuff. How long can she float like that?

Some cichlids do same. Maybe more than accomadating subterminal mouth. May also present more cryptically colored dorsam to would be predators.

She does it as long as she wants. I have seen her remain in that position for at least a half hour as I do visual checks then prepare and distribute the food to all of the tanks. But it's hard to say exactly how long because she usually starts prior to me entering the room.

Great photo. Is it hunting or just rusting?
Dusky darter (P. sciera) do the same thing (I believe these species are very closely related), esp around woody material (in the wild and tank). I've found them doing this in the St. Francis River in MO and Paint Creek in OH. I had a 3 pack that would just roam upside down all day long on a very large piece of driftwood that I had in my 100 gallon. And they'd wait for the food (bloodworms and mysis) to get hung up on the bottom sides of the wood.
I've not spent near enough time snorkeling in waters with blackbanded, but I would suspect they do the same.

Yes I know that. That is why I said the fish is adaptable.
