I don't have an open tank, this is research for a future plan.
What's the smallest native predatory fish that actually looks like a predator? As in, any random person can look at it and say "Oh, that looks like a hunter." I'm looking for something maybe along the lines of a pickerel, and I'd prefer if it was something native to Texas or a nearby state. I'm really just looking for something that doesn't need a very large tank, preferably something I can train onto frozen foods.
