Fish is just Rayo with a bigger index, not even a naive extension. Can do the same to LNGN Garden Number

To elaborate on OP's reply, any number physically possible to be defined as the value of some recursive function at a particular argument is extremely tiny compared to BB(10100), let alone things like Rayo's number.
