i found i can catch any fish pretty easy. i have caught a wrasse, tang, blenny, pygme angel even a dartfish using the night stealth method and a hemostat. hemostats are great for doing weeding too, i cleared my tank of bryopsis in a weeks time picking every piece i seen. the fish i just sneak up on them and clamp onto the tail, being night time you can take your time and aim exactly where you want to grap him so you dont hurt him, too much. works great.
