ok, so i was fishing with my friend in a very small little pond in new jersey. i’m pretty sure it was man made. there are sunfish, some bass, turtles, etc… all of a sudden i saw this HUGE black fish come out of nowhere. it turns out that my friend has seen them but doesn’t know what they are. it was all black and appeared to have vertical stripes on the side of it that are slighter lighter in color. This fish was long but not thin at all. they had a lot of “girth” to them. they almost looked like catfish but i didn’t see any whiskers and they lacked that flatness that catfish have to them. another weird thing is that they traveled in schools of 3 or 4. (only so many could fit in this pond they were huge) if anyone could help identify this fish or give me a general idea as to what they were i would greatly appreciate it! thanks in advance
