Close enough, this is the northern cavefish (Amblyopsis spelea) from Indiana and Kentucky, it is considered endangered because of it's limited habitat. It gets at max to around 4" long. Go ahead Gamefishin.
Alright I've been messing around long enough but still not familiar with those scientific names you guys are teming these fish with. I'll just go by the "English" version of their names if you know what I mean.
Here's two pic of the same fish......$20 bucks you guys get it wrong....other than sandtiger and guppy.
