Remarks: Green Line Lizard Tetras, sometimes referred to as Slender Tetras, are torpedo-shaped characins with a translucent or green body color with a neon gold stripe along their lateral line. They look best when kept in groups of 6 or more, and they will make great tankmates for most South American cichlids such as Angelfish orGeophagus. Some reports indicate they are fairly herbivorous and will eat aquarium plants, but there are other reports that contradict this. Large-leaved plants such as Swords and Cryptocorynes should be safe, but fine-leaved plants such as Rotala may be nibbled.
