Description
The Pyrrhulina filamentosa is a peaceful, small South American characin known for the elongated rays on the anal fin of mature males, giving them a distinctive filamentous appearance. They are often found in slow-moving, blackwater environments and thrive in well-planted aquariums with stable water conditions. This species is an excellent addition to a peaceful community tank.
