You mean like this one? Pure coincidence right. Yep. Coincidence.

This accusation, that Catholics worship the Babylonian fish god Dagon, comes up regularly with Catholic bashers.
The “proof” of this is that the mitres worn by bishops in the Catholic Church resemble the upturned mouth of a fish is risible, but gullible people actually believe it.
There are many faults in this argument.
1. According to the world renowned Encyclopaedia Brittanica, Dagan (Dagon) was the god of crop fertility (not fish), dagan being the Hebrew for “grain”.
Dagan, also spelled Dagon, West Semitic god of crop fertility, worshiped extensively throughout the ancient Middle East. Dagan was the Hebrew and Ugaritic common noun for “grain,” and the god Dagan was the legendary inventor of the plow. His cult is attested as early as about 2500 bc, and, according to texts found at Ras Shamra (ancient Ugarit), he was the father of the god Baal. Dagan had an important temple at Ras Shamra, and in Palestine, where he was particularly known as a god of the Philistines, he had several sanctuaries, including those at Beth-dagon in Asher (Joshua 19:27), Gaza (Judges 16:23), and Ashdod (1 Samuel 5:2–7).
Dagan | Semitic god
A possible etymology of the name Dagan from the West Semitic/Ugaritic root dgn, which can be translated as 'grain', and the Hebrew dāgōn, an archaic word for 'grain' (Black and Green 1998: 56), has tempted some scholars to assume that he played a role in vegetation/fertility, which might be confirmed by his son's, the West Semitic deity Ba'al, role as a vegetation deity (Black and Green 1998: 56). A 4th century AD tradition which places Dagan as a fish deity is erroneous (Black and Green 1998: 56).
2. Again according to the world renowned Encyclopedia Brittanica, Ea (Greek Oannes) was the Mesopotamian fish god.
Oannes, in Mesopotamian mythology, an amphibious being who taught mankind wisdom. Oannes, as described by the Babylonian priest Berosus, had the form of a fish but with the head of a man under his fish’s head and under his fish’s tail the feet of a man. In the daytime he came up to the seashore of the Persian Gulf and instructed mankind in writing, the arts, and the sciences. Oannes was probably the emissary of Ea, god of the freshwater deep and of wisdom.

Here is a bit of fun:
John the Baptist's name (John) in Greek is Oannes.
Interesting! Just a co-incidence?
And John baptised in water in a river where fish were!!!!.
Do you think John the Baptist was actually a pagan fish worshipper?
Now things get murkier. Jesus was baptised by John. Was that a baptism into John's fish worshipping cult?
That would explain why Jesus could point out where Peter & other could make a big catch of fish (Lk 5:6, Jn 21:6). And Jesus said Peter would "fish for people". (Lk 5:19)
Perhaps Christianity is just a Babylonian fish cult.
Do you see how silly these sort of comprisons can get?
Now back to the faults of this claim
3. The relief picture of the “fish god” most commonly shown is actually from the Assyrian city of Nineveh (not Babylon), and was discovered in the excavations of the 1840s by Austen Henry Layard. (see www.gutenberg.org/files/39897/39897-h/39897-h.htm)
4. Similar does not mean equivalent. It is the logical fallacy of Cum hoc ergo propter hoc (with this, therefore because of this). That there are similarities between two practices occurring at similar times does not mean that there is a causal link between them. This is even more ridiculous when the supposed common practices are at a distance in time and space.
5. Nineveh was destroyed, razed to the ground around 612 BC. The mitre in its current form did not appear until the 12th century AD. It developed from a round headdress like the Jewish priestly turban & as worn today by Eastern Orthodox priests. There are therefore some 16 centuries between the destruction of Nineveh and the supposed appearance of the “fish mouth” shaped mitre.
6. No other similarity is presented between the supposed cult of Dagon and Catholic practices. The whole charge rests on this singular and highly fanciful similarity
