Seriously, I think the point of the Fish numbers is that each one is obtained by a different means than the last, with the succeeding number being vastly larger than the one that came before it, not to dissimilar to the well known fish-eat-fish concept:

In addition, perhaps Fish is also meant to illlustrate the many waterlike paths of discovery and learning that can be used to eventually pool down into the hollow of number making. Water is actually a really good metaphor here, because since the FGH and Fish number expressions only land us in extremely specific portions of the numberline, it as if all googology starts out on a single flat surface, eventually running rivulets of creation down to a few distinct hollows. The hills that this wat'ry discovery can not not run up against are either too tall to ever comprehend, or just too specific to ever get a handle on in a finite lifetime or finite resources.
