it seems like everyone says needle nose 'gars' are super jumpy and run into the end of the tank, but mine is friendlier than my clown knifefish(who is pretty friendly). the gar rushes to the front of the tank when i come downstairs and if i walk past the tank he follows me around it. it sorta funny seeing sd most ive seen hide from people
mine were the same way came to the front of the glass they noses got a little ruffed up from swimming against the glass but thats the only thing that happened to them weren't really jumpy at all
