One bit of confusion for me is how many of them were newly discovered fishes and known fishes for which taxonomy had not been formally conducted.

Several aquarium species have been described from unnamed preserved specimens in museum and university collections. This most often happens when an ichthyologist endeavors to revise a genus and scours the database of collections for unnamed specimens that might belong to said genus.

I wonder if these are ones that are very closely related to something we know, but a fin on this one is a little longer or something like that - or are there really new- never seen anything like it type fish?

I think the cave fish tend to be novel since it is a habitat only relatively recently explored.
