Hi everyone, today i just bought a freshwater needle fish and he is about maybe 3 or 4 inches and I'm not sure if he is just nervous or if he is being bullied by the other fish i have in that tank, which include 3 angel fish, a severum, blood parrot and manganese cichlid. My tank is a 37 gallon. I also have a 10 gallon tank that is empty and i can put him in there if he is being bullied and move him back when he gets bigger.
