I got the two from Browns in East Longmeadow, they get odd fish every once in a while and have always had good luck with them.I am assuming they are from the same clutch, they are identical sizes and features, just different markings, they recieved both and were told they were clown knife fish. I will attempt to get a picture of them together tonight, I am just not wanting to disrupt there setup too much, as they are eating well and hunting each night.I am pretty sure it isn't a asian knife as they have more rounded features and less of a hump. I'll get a picture.
