Yes,the goldfish is a persian popular symbol; usually a pair of fishes are shown on many persian / afghan coins.
from the net : "Goldfish, it is the symbol for Pisces also known as Fishes, which was relevant in traditional Persian calendar. Iranians put goldfishes in Haft-Seen to indicate that the new year starts from this month. Nowadays it is also a symbol for Victory, Exhilaration, Blessing, etc."
in center the two curved lines are clearly swords.
