Red Phantom Tetra Hyphessobrycon sweglesi

Native to Colombia and Venezuela, these full-bodied tetras sport a diamond of deep black on their sides, surrounded by a wam metallic orange. Males will develop a very pronounced dorsal fin as they near maturity, and will show off a much deeper coloration at spawning time. In the wild, these fish inhabit acidic, slow-moving waters, and will do best in well-planted aquariums that mimic this. Like all shoaling fish, they will thrive in groups of six or more.
