I had problems with Corydoras loxozonus, they never adapted, they just started dying one day one by one, I tried it only a couple of times, and I haven't seen them available since then. I have no plans to add fish at this time, I only have a 25 gallon tank, maybe 27, so I have to figure out how to increase the capacity, I'm going to relocate the loaches and they will not be with my future angels and my tetras, either, I would like to hook up a large tank (very large if possible), a sump and a very large container for my loaches and maybe larger fish that are compatible, I'm taking a look at the 300 gallon Rubbermaid containers, and thinking how to connect all that is what I focus my attention on, and a separate QT tank.
