my goldfish pecks at my arm the whole time haha because he hand feeds so if i put my arm in the move something or something he just pecks the whole time lol feels kind of cool lol
My loaches seem to like trying to nibble on my fingers. My killiefish will do the same. Most of the schoolers kinda hide from me, but will relax and come out in the open once I've had my arm in there for a minute or two.
I believe only the SW form of fish TB is contagious to humans. Although, I'd rather be safe than sorry! I use gloves now but before that, my zebra danios would nibble my hand and swim through my fingers. It really tickled! They also tried to get at the stuff in the siphon every time I'd gravel vac.
