So i came home last night and as a surprise my mother and wife had bought me a striped eel and a 2" black ghost knife. Now i already have a 7" BGK that pretty much kept to itself but does not like the new BGK in its log. Now I set up a cav for the baby BGK on the other side but what I'm worried about is the bottom fin on it is feathered not one solid fin. has anyone seen this before? What is the likely hood m BGKs can coexist also cause I would like to keep both of them but am a little nervous. any suggestions?
