Hello everyone , My name is Nathaniel and I'm 18. I'll be an owner of a 100 gallon saltwater aquarium. I would like some suggestion of of type of predator fish would be good for this aquarium. I'm a first time saltwater aquarium keeper. I am willing to take criticism. I know I sound crazy but I have worked with predator fish before. Although it was only for a 3 weeks. A friend's banded Cat Shark wouldn't feed. I got it to feed by giving the little baby more hides and small food items.
