You mean Ember Tetra?
🙂 I got 11 of them in a not fully grown heavily planted tank.
🙂 They love surface vegitation, dimmed lights and as Iain says moderate flow. I have my Co2 spot on at the turning point 6.3/6.4 if i go 6.2 i see their gils move. I can't say they are that skittish they only team up and hide when i work in the tank. For the rest of the day they are exploring the whole tank in small groups or a pair. I have an adjustable outflow and i notice they realy are sensitive to flow changes, if i change it drasticaly to half speed they school up for a minute or 2 then start exploring again, the same when i go up full speed again, but then they school up in the high flow corner of the tank. My high flow is still moderate because i use the ball shape lily.
Also using a programmable dimmer and when the lights slowly go under the 20 % they realy come to life, then you see what they realy like. They show heirarchy, chasing and playing sham battle and shooting trough the tank low under the surface vegitagion, the girls are most cheeky and bossy. It's like seeing them play hide and seek in the hanging Salvinia roots. At highlight during the day they rather stay mid to few inches above the bottom, sometimes under the nymphea leaves under the surface. Alway on guard. If i move to much in front of the tank or take a cloth to wipe the window they emidiately school up, dive down and search a corner. Mostly deep down in the high flow right above the substrate, like a predator is in its disadvantage there and it is. Mostl predators are oppertunist hunt on sight hiding in the bush. So down dark they are safer

That's what i experience with my Embers.. They are together with 7 Pygmae Cory's, 6 Amano Shrimps and 6 Oto's, so they have nothing to worry about but me.
These are taken a few minutes ago during high light..From left to right and as you see Embers all over.

I breed my own Daphnia and once a week i shut down the pump for an half an hour and feed them the live baby Daphnia. Then you'll see they are predatory themselfs, they love to hunt and kill the big once in teams. Little backstabbers they are..
