Most Wolfs just chill during the day and hunt at night. I have a 12" Hoplias Australis that has no hiding spots but just chills in the corner and soaks up the sun all day long. Hoping as he gets older he will start to swim around more but I have other fish in the tank to add more activity. Have Cory cats, belly crawler pike, spotted cat,big craw fish and giant danios all in the tank with him.
