Anyone have experience with these? I have a 180 with a Ctenopoma, Anostomus, Denisonii barbs, and 3 stray zebra danios. Looking to add a Flagtail Prochilodus, and trying to decide between a school of Chalceus, a school of Hemiodus, or a single Chalceus and a school of Hemiodus. Can't find a lot of info on the Hemiodus though.
Hemiodus gracilis

Thanks for the info! I've seen them in 2 different LFS in the past month and both times they've managed to catch my eye... Do they tend to hang out at the top, middle, bottom, or everywhere?
If memory serves, Chalceus get to be close to foot but my main concern with these fish is that they tend to attack each other or other fishes to a point many tankmate's scales are lost, that is if not swallowed/eaten. I would be worried with smaller denisonii barbs and other smaller specimen.
Hemiodus on other hand are very peaceful/shy fish, ususally hovering mid to top but can vary according tankmate's behaviors.
They tend to twitch (best term I could use) as they hover in angle where some fellow hobbyists have thought such twitching was due to infestations, sometimes causing more damages/losses when unnecessarily med/overdosed.
I found many sites on this fish. Try again.

Even smaller chalceus (2-3") did enough damages to other similarly sized tankmates from what I observed but more so on each other. Even when I fed them well.
I'm considering Chalceus erythrus, which maxes out around 8". I've been reading that the Chalceus can get pretty scrappy with each other if kept in less than 6, but haven't seen a lot about aggression toward non-specific tankmates if kept singly.
Depending on books, C. macro and C. eryth may be same fish but I leave that up to each individuals. (sometimes received ones with yellow fins as C. macro, not that they are same fish) Even some books suggest 12" on C. eryth.
ALthough have kept school of C. macro in groups of 2 dz or bit more in 6' tank, never kept them singly thus you may have answered your own questions. But beware of its aggression regardless of its size, especially with fish that roams same upper region. They are not like other bullies but behaved/attacked similarly to that of barracuda and/or other similarly behaved fishes (lightning speed, sort of).
Have fun & Enjoy new tank!
