Heckel Discus

The scintifiec name for Heckel Discus is Symphysodon

They found mostly in Brazil Rio Negro, They were the first discus to be discovered and can be distinguished from other discus types by the three black vertical bars.One bar runs through the eye and another through the caudal fin, but the most prominent bar runs down the center of the body.

Other discus also have bars in their natural forms, but only the Heckel Discus displays a broad dark central bar.

It's named after Johann Jacob Heckel and is the most difficult discus to keep, because it likes somewhat softer (and lower pH) and warmer water than the other species
