iNat is a place for uploading observations of one’s own encounters with wild organisms, it’s for recording and sharing personal experiences. The fish examples that @gustavomorejon mentions seem fine to me, but please use the date and location of collection, as others have said. A personal insect collection of insects you collected would also be fine.
iNat shouldn’t be used as a place for uploading museum collections, there are other platforms like iDigBio for that purpose.
