The arapaima is the kind of fish that can make an aquarium visitor stop mid-walk. Its long, thick body and large, armor-like scales give it an ancient appearance, while the deep reddish markings toward the tail add flashes of color as it turns. One of the most interesting things to watch is how it breathes. Arapaima must regularly rise to the surface and gulp air, creating a quick, noticeable movement in an otherwise calm tank. They can grow to enormous sizes in the wild, so seeing one up close gives a better sense of just how substantial this freshwater predator is. Keep an eye on its mouth too. An arapaima can suddenly open wide to swallow fish and other prey with a powerful suction. In the Amazon, this ability to breathe air helps it survive in warm, oxygen-poor waters. In an aquarium, those quiet trips to the surface become a simple behavior that makes this unusual fish much easier to appreciate.
