and the cheeks and runs across the body up to the base of the
caudal fin. The Heckel discus is distinguished by the fifth prominent
vertical bar (see pictures below). The eyes are gold to red. The
ventral fins are red orange and they have a blue longitudinal
band. These discus come from Rio Negro (Brasil).
The Blue Face Heckel ( BFH)

the head in solid blue color. Some specimens have this solid
condition through front half of the body. These discus come from Rio
Unini and Rio Jaua (Brasil).
The Heckel Cross is a mix
between a Heckel and a Blue, mainly from the Rio Madeira system. These
fish have different characteristics, some look like a standard blue
with almost no striations in the body but with the fifth Heckel bar,
other look like a Royal Blue with the fifth bar also.
