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.

There are a few things. A lot of fish are known to local people, but that knowledge isn't shared.
Three day ago I talked with a knowledgeable African fisherman who told me about all the fish in the river, using their Latin names, Bu when we caught 2 inch Epiplatys in the same nets as lampeyes, he hadn't noticed them because his interest was feeding people. Humans...
As we destroy rainforest regions, we open them to remove their trees and minerals, and for a short time, fish species that haven't been seen before become reachable. That's where a lot of what we call new come from, with tetras and such.

On a 2 week trip to Gabon in 23, we found what may someday be 7 undescribed species, if some grad student gets around to them within 50 years.

I'd argue we know nothing, or close to nothing, about the world we live in and the life in it. We've barely scratched the surface. In many rainforest and rough terrain regions in warmer areas, there are lots of unknown things. They aren't new, that's just us talking like animals are products. What we call 'new species' can be far older than us. We just haven't paid enough attention or known how to figure them out.
