Quite lucky, a local was selling some chaetostoma! I got a deal on a group of them, so I opted to buy the group in the hopes of finding the opposite gender for my original one.
Definitely got mixed genders, they're currently in quarantine though.
My original chonker

Then the newbies



They're cute and look to be good shape.

By time they're done QT, the tank should be ready for residents.
I'm fairly sure fish 2 is male, based on the pointed pelvic fin extensions. Fish 1 is female.
I'm hesitant to decide on original fish and fish 3 if they're male or female, fins are a little intermediate.
I will keep my original, but aiming to keep 1m:2f and I have a friend interested in taking one of the extras after quarantine. I made a post on planet cat as well to confirm the genders of the newbies and also original. I really enjoy the chaetostoma I already have, and they make a fantastic cold water pleco for a river setup, they like it cooler and faster water to thrive.
In the bundle deal one is a clown pleco haha... little guy will be going in my blackwater setup once he's out of quarantine as well.

Still many options. Exploring many of them. Several tetra species don't mind low 70s. Just a matter of seeing what's available to me, what's compatible with the tankmates, and what won't break the bank.

I'll be sticking with south american fish for thos setup. I am definitely finding I like to stick with regional setups, I find I enjoy them a little more.It's great you have enough tanks to make the switch for all your special paleatus fry. Many upper level fish to choose from, lots of different barbs first come to mind, a bunch of smaller 1s (Odessa? Octozonas? I'm not sure of the temps)? Or go big with denisonii. Maybe a different danio species? Kyathit? I think even your rasbora sarawakensis might work in there too.
I'm sure you'll find a cool species to keep (pun intended, lol).
