When we think of barracuda's we often think of the Great Barracuda which reach around 5 feet and are absolutely not suitable for a home aquarium. But there are other species of barracuda like the yellowtail barracuda (Sphyraena flavicauda) which reaches a max of 24 inches and on average 14-16 inches or the striped barracuda (Sphyraena obtusata) which only reaches a max size of 21 inches. Some tangs even grow to these lengths and I imagine require the same amount of swimming room. I especially love the yellowtail barracuda. Has anyone ever kept one and can you even buy one? They seem like a perfect fit for a predatory reef granted you'd have a large enough aquarium but I can't find information anywhere.
