In analogy to the word formation of *vegetarano* - *legomo*, can I have *pesketarano* - *fiŝo* which does not use the corresponding root of *fish* in Esperanto? Or *fiŝ-vegetarano* should be preferred?

I wrote a small paragraph for explaining it: 

> 
> "Fiŝ-vegetarismo”(Pesketarismo) estas la maniero de sekvi dieton, dum kiu estas evitata manĝado de viandoj krom fiŝaĵoj.
> 
> 
> 

Does it make sense?

Sincere thanks.

See the wiki page for [Pescetarian](https://en.wikipedia.org/wiki/Pescetarianism).

Updated: I have changed the word in the description from *-arano* to *-ismo* to indicate Pescatarianism for clearer understanding.
