No. For example: 4181 / 37 = 113 so it can't be prime. But 4181 is the first composite number in the Fibonacci sequence with a prime index. ;)
The first Fibonacci number greater than 23 is 34.

The first composite number is 4.
the first seven Fibonacci numbers are 1,1,2,3,5,8,13. 13 is a Fibonacci number.

The first four-digit Fibonacci number is 1597 - equal to 610 + 987.
A Fibonacci number, Fibonacci sequence or Fibonacci series are a mathematical term which follow a integer sequence. The first two numbers in Fibonacci sequence start with a 0 and 1 and each subsequent number is the sum of the previous two.
According to the link, zero is the first number in the series.
Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).
