Everyone says that peacock eels arent as social as ZZ eels. My peacock (very light colored, i dont know if that makes a different) has been handfed since ive had him and is very social at night and sometimes during the day. Along with my peacock eel are various barbs, angel fish, senegal bichir, dragon goby, and a tiny banjo catfish(NEW). they have lived peacefully for several months in my 55 Gallon.
