What is this fish?!

You should see this species in a shoal in a tank with good floating plants to shade the light. Every colour of the rainbow is reflected along the sides. I don't have video capabilities, and my camera is too cheap to get good fish shots, or I would post some of my group. But here are a couple photos from online that are not too bad that may give an idea. [And yes, that is a male Congo Tetra in that video.] When acquiring this species, a group of male/female is best; the ratio is not so critical, but the presence of a couple females will invigorate the males, and when they display in pairs, sometimes a trio, of males, they are something to behold.

Oh wow!!! Super gorgeous!!! Do they have teeth?!?! Are they predatory?
Byron you have a school of these? If you ever upgrade phones and get good video capabilities please post!

I've never seen these fish before!
 
Thank you, I'm really looking forward to getting a bigger tank at xmas and getting more of these fish. In that video, the light wasn't great and the fish looked a bit orangey but it isn't, it's silver in colour and as you said it reflects every colour of the rainbow under the light. Definitely my favourite fish in the tank.
Thank you for all your help

I look forward to seeing more when you get them! I thought it was a small fish from the original pic but after seeing the video I can see it's a decent size. And after seeing the pics Byron posted I see they have teeth!!

Teeth?! I must have a closer inspection!
 
Yes, they are characins, which includes all tetras, pencilfish, hatchetfish, pacus, headstanders, the pirahna...they all have good sets of teeth. But having teeth doesn't always mean aggressive. Most fish have teeth, sometimes in the mouth (dentition) like these, sometimes in the throat (termed pharyngeal).

Congo do get a decent size, up to 4 inches, but they are very peaceful. I had a group back in the 1980's, and I currently have a group which I've had for five years now. I had 5 males/5 females, but lost three of the females to a bacterial issue about a year ago. So I'm left with 5 males/2 females. The males run relay races down the tank when they're in the mood, just two side by side, sometimes a third tries to join in. Mine spawn quite regularly and often, but being egg scatters the other fish easily eat the eggs as soon as they are released among plants.

Here's a photo of my 90g with these in the middle, not the best photo given my camera. The males are larger than females, and my males are now at 4 inches, including tail.

Mine ate fairly large live food. Congo and emperor are my favorite tetras.

Omg that set up is just beautiful!!! All those lush plants!!! They sound like really great fish to keep! Thanks for sharing!
 
ooooh please post a picture or video! I'd love to see them!

Did you get them at the Aquarium Center?
Hi Jen,
Yes, I got my most recent ones from the Aquarium Center, probably six months or so ago. I think they just got in a new batch, because I saw them in the "new arrivals" section on the website. I may get a few more in the future.

Not the best picture. (Not as good as yours!) It is difficult taking photos of my fish because the back of the tank is a mirror...

Oh wow!! They look great!! So does your tank! I just saw on Instagram they got in the teeny little scarlet banditas (spelling?!). Such little cuties.
