The Silver Arowana (*Osteoglossum bicirrhosum*) is one of the most impressive freshwater fish that can be found in a home aquarium. Known as the “dragon fish” due to its archaic appearance, powerful body, and large scales, it consistently attracts the attention of aquarists worldwide. However, keeping this predator requires not just experience, but also a readiness to provide it with a truly colossal amount of living space. Before deciding to purchase a fry, it is necessary to realize that the arowana is not just a large fish; it is a fish that requires monumental conditions.
