The Severum (Heros efasciatus) has been a mainstay in the aquarium hobby for decades. They grow large enough to act as centerpieces, but they are not tank-busters, and they come in a variety of color patterns. Severum have a very elaborate body color, ranging from green to blue to red depending on light and mood. These ones in particular are a man-made variant that vary in color from green to turquoise. They are typically peaceful, though aggression will surface if pairs form.
The Severum your will receive will be approximately 3/4” in size.
