Hello, I’m thinking about getting into saltwater but I’m not into small colorful fish. I like aggressive, predatory, and dangerous fish. I don’t have the budget for a huge aquarium that most of them require however. Any recommendations on good fish for anything 55 gallons and smaller? I really like stone fish but I’m not sure if that fits what I can do space wise. Dwarf lion fish might work. Please let me know of any fish that might also fit the build I can do freshwater too.
