that is a PERFECT example of just why i LOVE barbs so much.
I know this sounds funny, but mine actually interact with me. they will swim up to my arm when i am messing with things in my tank, and nibble on my knuckles, pull my arm hair and ravage my scabs.
If i have the slightest cut on my hand/arm them tear into it, often times ripping my scab off or making the wound larger, pulling chunks of skin off.
I know that sound gross, but.....
