Did god create animals before he created fish and other sea creatures?

Yes

Another Answer:

No, but birds (part of animal classification) were also created on the 5th day while land creatures were begun on the 6th day:

Genesis 1:20-24New International Version (NIV)

20 And God said, "Let the water teem with living creatures, and let birds fly above the earth across the vault of the sky." 21 So God created the great creatures of the sea and every living thing with which the water teems and that moves about in it, according to their kinds, and every winged bird according to its kind. And God saw that it was good. 22 God blessed them and said, "Be fruitful and increase in number and fill the water in the seas, and let the birds increase on the earth." 23 And there was evening, and there was morning-the fifth day.

24 And God said, "Let the land produce living creatures according to their kinds: the livestock, the creatures that move along the ground, and the wild animals, each according to its kind." And it was so.
