COMMENTS
If n is a member of this sequence, any reordering of its digits is also a member of this sequence. Since A000045(0) = 0, any number is the sequence can have an arbitrary number of zeros; hence, the numbers with zeros have been omitted as trivial.
EXAMPLE
23 is a member of this sequence because F(2) + F(3) = 1+2 = 3 is a Fibonacci number.
PROG
(PARI) isfib(n)=for(k=0, 2*n, if(fibonacci(k)==n, return(1))); 0
for(n=1, 10^3, my(d=digits(n)); if(vecsort(d, , 8)[1], my(s=0); for(i=1, #d, s+=fibonacci(d[i])); if(isfib(s), print1(n, ", "))))
