I just moved my 4" delhezi from his growout tank into a 55gal with a 6" Senegal. I have been watching closely for the past 40 minutes and have not seen any aggression whatsoever. The delhezi occasionally follows the sen around like a puppy dog but the Senegal is just going crazy. As soon as the del gets near, he zigzags around the entire tank and tries to jump out! Is this normal?
