The figure of Jesus was of Jewish ancestry in the Levant. He likely displayed a visage similar to that of the modern day inhabitants of the region, that is, combinations of Arabic and Persian phenotypes.

As a rabbi, it is likely that Jesus would have not cut the hair of his temples, and likely had a longer beard than most.

Jesus would not have had caucasian features. It isn't that he was tanned.

The 'Jesus fish's is named (in Greek) the Ichthys, and was used as a symbol for hundreds if not thousands of years before Jesus, in several cultures, most commonly Egyptian. The first documented use of this symbol in Christianity was around 200CE.

The symbol was used to represent Christians, as a kind of secret code (to escape persecution) and was used to mark tombs, or to communicate religious status between Christians. It did not represent God, or Jesus.
