That's not a swamp darter (or if it is it has odd pattern and shape) and not all darters stay that small. Quite a few get to 5" and very thick.
ShadowBass;1244653; said:I meant most "standard" darters. Logperch exhibit some really neat behaviors, though I have no idea whether they'll do the same in an aquarium since I've only observed them while snorkeling. I had one following me around one day because I was turning over rocks for him.
They kind of reminded me of yoyo loaches.
