What animals were in Eden? Is there any mention of actually what animals were in Eden? Is any mentioned beside the serpent? Is there any  mention of what animals were eaten, if any?
No, only that after God created Adam he was tasked with naming the beasts of the field and all the birds of the air: “He [God] brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name.  So the man gave names to all the livestock, the birds of the air and all the beasts of the field” (Genesis 2:19-20).

The only mention of eating animals is in Genesis 9:3 and this is after Noah and his family emerge from the Ark: “The fear and dread of you will fall upon all the beasts of the earth and all the birds of the air, upon every creature that moves along the ground, and upon all the fish of the sea; they are given into your hands.  Everything that lives and moves will be food for you.  Just as I gave you the green plants, I now give you everything”.   This suggests that meat was now permissible to eat.

There is no clash with the creation account that I can see.  All the land, sea and air creatures had been created by the time God created Adam.
