This is a bit off the topic but i just noticed yesterday that i can hand feed my cleaner shrimp. Its just amazing how he comes to my fingers and takes the food out of my hands.
My Sailfin tang won't eat algae off the clip. He only eats it if he has to chase it, Like if a piece came off the clip and the shrimps, forget it, no fear. I was actually going to post his unusual behaviour but you beat me to it. He once chased a free floating bristleworm till he tasted its sting.
me too, all my fish even the neon gobies will eat from my hand. the copperband follows me around the tank when I'm moving coral.
the only fish that stays away is the flame angel.
