User blog:Martialmaniac/Indoor Fish, not Conjuration?

Was it ever confirmed that the Indoor Fish is a conjured animal? Because thinking about it, it is most likely an Emission + Manipulation ability. All Nen beasts that have appeared so far were emitted, not conjured. The only living being created through Conjuration is Kastro's double; however, it was said to be exactly like Kastro, meaning it was precisely like any other human being. On the contrary, the Indoor Fish can fly (ok, Manipulation), what it eat disappears, survives without water and for some reason dies as soon as the room is not sealed any more. It is clear that a being like that is not "real". So, would you agree to at least consider it an "Unknown" Nen Type?
