Fish from that region are hard to pin down temperature wise. I know the few killies that overlap with their range like it much hotter than I would offer in a tank. Reports seem to vary based on when the fishers were there.
Temperatures around the type locality can hit 43 (if I can't get water temp info I check the annual weather for the type locality for the species). Water temperatures may be cooler, but probably not incredibly so. The range of 43 to a low of 25 is nasty, but seasonal. The fish of the region probably experience seasonal variation, but a tank at 28c is probably okay. Probably. Maybe they need the fluctuation.
I played with my other online tool, google earth and as I expected, that ain't a treed riverbank. So it would get the full force of the sun in the dry season.
It doesn't seem to be a stable year round climate like SA Discus. That won't be a biotope tank!
Parailia pellucida get a decent size. How active are they supposed to be? I've never encountered them in person.

What i read is they are moderately active but hang near the substrate/plants at the bottom unlike the other species. My guess is they aren't a good fit; was mostly hopeful for something that the discus couldn't eat and cardinals are sort of slowly being eaten (I think).
The problem with cardinals is they are sold so small. My not overly successful attempts to breed them in numbers suggests they are sometimes under 3 months old in stores. Once they get to adult size, they would be safe with discus, but if they're wild caughts, they hatch around December and are sold in February/March, and farmed ones are really rushed to market. I had full sized wild caught scalare not eat any cardinals in a 75, but the cardinals were 2 years old. You almost have to have a cardinal growout tank, and add them as they get big enough. It would be like a large QT tank, but QTing from predators.
If you compare aquarium-common tetra growth with Cichlids, there's no contest. My Pristella maxillaris were the size of their parents in very little time. Their growth rates are turbocharged, which makes sense given the predators around them.
I don't heat my tanks except for breeding, so I look in the cool water direction. But there must be high bodied small tetras that like Discus habitats. They're surface fish, but hatchets?

AI this morning also puts ember, and rummy noses, in the group of tetras that thrive in warmer waters... my adult zebra lace angel hunts cardinals, eating them, unless they are jumbo... I also have rummy's in that tank, and it's always left those alone...
My brain jams on tiny little embers (fast food for angels). When I first got them, they were called amandaes, and ember only came later. One of these days I'm going to confuse everybody by using the old common name.
I've got it though. You need Iguanodectes geisleri or gracilis. I had gracilis with my Discus, back when the world was young.

hemiodus gracilis aren't compatible as they prefer cooler temps mid 70s - i have 20 in my 600 and quite frankly they are too large for a 200 (6 foot long).
Again i'm finding that iguanodectes geisleri prefer cooler temps... so not sure either of these are good choices for discus.
Also my discus are significantly larger than any domestic angelfish will reach.
When I first got my h. gracilis i was keeping them at 78 and a year later some 'experts' advised me to lower the temp to 76.

The temperature range I found for mine was 23-27 (I don't speak fahrenheit so I'll be lazy and let you convert - sorry). That's in both seriously fish and more importantly, fishbase.
Parailia pellucida can be bigger than Iguanodectes, so I thought you were looking at that range too. It may be that Iguano need more flow though. That could compromise a discus set up.
A lot of people (as you know) don't combine discus with other species. I have a friend who used to collect wild discus, flashlight hunting in the flooded forest, and they were surrounded by other species in large numbers. No one ever seems to like listing them.

27c is 80f though that is the high end and i try to keep fishes more towards the middle. Yea that is the real thing is i can't find if any dithers are found naturally with discus. I was hopeful some high body tetra or similar live in warmer waters - so far the closest i've found are Dicrossus and rams but of course i don't want a tank full of fighting cichild. I do wish the aquarium was larger - at least 400 gallons but that is another issue.
If i ever keep discus again i will find a way to get them into one of my larger aquarium (which are right now not temperature compatible).
how about some pencil fish???
seriously says these can go to 28C
beckfordi to 27C

Some of the fish from link one, like the Cory group, are from shaded feeder streams for the Rio Negro, but a lot of these are fish I have seen in the same boxes as nice wild Discus.

I love pencils, but they are bite sized. If the discus are eating cardinals, then they have discovered the joy of pencil shaped tankmates.how about some pencil fish???

beckfordi to 27C
maybe Leporinus??? kind of like a bigger pencil???

Hum the paper mentions a lot of hemiodus species just not gracis. I was kind of hoping for a headstandard. Most of the fishes mentioned in the first link are cichild or catfishes (pleco). It is true a *lot* of pleco like warmer temps esp the high 80s found iwth heckel. They also mention rummy which are a bit faster than cardinals and tend to be a bit more wary of larger fishes (I have a group of 20 or 30 with my geo in a 500). Sadly i've found a few bit in half...Some of the fish from link one, like the Cory group, are from shaded feeder streams for the Rio Negro, but a lot of these are fish I have seen in the same boxes as nice wild Discus.

I have a nice cat with the geo a port something or other Dianema urostriatum; but again they prefer a bit lower temp also they are kind of a lazy bottom fish spending most of their time sleeping under a log in a large group. At least the ones i have. Oh well maybe i should go with 50 ember tetra and see how long they last
