you can add lots more to your tank. I have a huge snowflake eel in my 92 gal
. 1 maroon clown, 3 tangs, 1 angel, 1 huge panther grouper, corals, mushrooms, etc.. My snowflake will not attack your hand in the tank unless you have food in it. My wife learned the hard way. She was talking on the phone while feeding a frozen cube to eel's tankmates not pay much attention. The eel must have been very hungry and went after the food in her hand thinking it was a shrimp intended for him. He chomped down pretty hard on her finger slicing it open. That was the last time she talked on the phone while feeding our fish!
