Can anyone help me to identify which is this fish?
It's rummy nose tetra, though there are three species sold under that name. The species most commonly sold as rummy nose tetra is Hemigrammus bleheri, and that is the one which looks most like your fish.

Petitella bleheri (Firehead Tetra)
Formerly Hemigrammus bleheri. The firehead tetra, Hemigrammus bleheri, is a characin from blackwater rivers of the Rio Meta and Rio Negro in Colombia and Brazil. Most fish sold as the 'rummy-nose tetra' are this species. Of the three look-alikes, with H. rhodostomus and Petitella georgiae, only...

Most rummy noses in shops are not the true rummy nose.

How to tell the difference between the three species sold as rummy noses
Petitella rhodostoma (Rummy-nose tetra)
Formerly Hemigrammus rhodostomus. The rummy-nose tetra, Hemigrammus rhodostomus, is a characin from blackwater rivers of the Rio Orinoco and lower Amazon basin in Venezuela and Brazil. This is the 'real' rummy-nose. Most fish sold under the name are the firehead tetra, H. bleheri, and the...

The false rummy-nose, Petitella georgiae, is a small tetra from the Rio Purus in Peru and Brazil and the Rio Negro and Rio Madeira in Brazil. This is one of three very similar species commonly sold as 'rummy-nose tetra', and the lack of a dark blotch at the bottom of the caudal peduncle is one...

Its a rummynose tetra.
Belong in groups of at least 6 forms tighter shoals than average tetra, gets around an inch and a half prefers soft acidic water an the upper tropical temp range of 76-82
Will fail to thrive in small numbers or singly. The red nose will fade in times of stress or when water quality is poor which is why hobbyist refer to them as canary in the coal mine fish and regularly pair them with expensive sensitive fish like discus. Require long tanks of atleast two feet as they are active back and forth shoalers. The longer the tank the better the larger the shoal the better. Good luck one of my favorite fish in the hobby

That is extremely cruelty to the fish...I dont know if they still do now, coal mine is not for fish...
It is a saying "a canary in a coal mine"
In the UK and probably other countries, back in the 1800s and earlier, they knew there was a dangerous gas that built up in coal mines which could kill the miners. They could not test for the presence of the gas. But there was another way. The bird canary was highly susceptible to the gas, so they took canaries in cages down the mines, and if the canary fell off it's perch, the miners knew they had to get out fast. The canaries would recover once they were taken out of the gas filled air, and they saved many lives. Later, the Davey lamp was invented and these were used instead of canaries.
Nowadays the saying "canary in a cage" has come to mean any animal that is affected first and alerts the other animals to any danger. Rummy noses are called "canary in a cage" because their red noses go pale if the water quality is poor, alerting the fish keeper that there is something not right with the water. Malaysian trumpet snails are another "canary in a cage" because at the first sign of poor water quality they crawl up the glass.

Sorry barry its a metaphor. Back in the day coal miners would take a canary down in a cage into the mine to warn them when the air in the mine was dangerous as the canary would die.
A rummynose tetra acts in the same way as a warning that when his nose fades the water in the tank has a problem.
Yea I know, but it still hurt fish.
What hurts the fish? Im confused?
I mean stress the fish.
They dont stress the fish on purpose. Back in the early days of fish keeping hobbyists didnt have ammonia test strips and liquid dropper water tests. They just had to guess so keeping rummy nose were a good indicator of when to change water. The hobby has changed alot since then as weekly water changes are encouraged and multitude of tests are available yet still rummynose tetra are still a good indicator fish and favored by aquarist who keep expensive fish to warn them there may be something wrong.
It’s definitely a Rummy Nose Tetras. These fish are very social and need to be in groups of 6 or more.
