So for some background info, its a 75 gallon heavily planted tank with lots of caves and driftwood hiding places, I've had a lesser spiny eel in there for several months and its gotten along with all the other tank mates just fine, I put a senegal bichir in just last night and the eel will not stop harassing it, it isnt really fighting or anything, the eel is just constantly right next the bichir, both are about 8-9 inches, I'm curious if there's a way to deter this behavior or if it'll go away with time
