my wolf is decently active compared to what everyone says about them, i slowly changed the night time and daytime, then he just started swimming during the day and half the night, he is kool, fast slender, teeth and messes everything up in the tank. he is baby still. almost 4.9 inches. and he beat up a 8inch oscar. a friend threw his oscar in my tank 9 me not knowing he was letting it out of the bag, he just bought it, next thing i know i freak out thinking my wolf is about to get hurt 5 minutes the oscar was in there, i run to the tank with my buddy to find his oscar barely able to swim sadly it died. the wolf fish just swam around staring at it dieing like yea this my tank gtfo lol. i was so proud of him.
sucks my friend had no idea that the wolf fish was in the tank. i forgot to tell him i moved him to that tank. so it wasnt his fualt. he thought it was empty. still.
