Given your ideal water, and the relative closeness of The Wet Spot in Portland...I would myself acquire some of the more rarer species. There are more than 160 described
Corydoras species, and all have identical requirements and behaviours (with a couple of exceptions) so the sky is the limit!
I remember back in the 1990's when my preferred fish store in Vancouver used to get wild caught fish every week, and the selection of
Corydoras was amazing. I was in cory heaven. I remember going in one Friday evening when the owner greeted me by telling me he had another shipment of adolfoi cories. I took a look at them and immediatel;y knew they were not adolfoi, but
Corydoras duplicareus which had been first discovered in the early 1990's and described by David Sands in the July 1995 issue of
FAMA. The store carried this fish magazine, and it was August of 1995, so I pulled out the article and the owner changed the sticker. They were the first of the species imported into Canada, and I bought up the group. It is still one of my favourite cory species. Photo below. It is usually seen as "adolfoi" in stores because that name stuck with the pattern after the unique
C. adolfoi was discovered in the early 1980's and named by Burgess (1982), but The Wet Spot will have them correctly identified I'm sure.
