Purple tetra at the center of the video

Six in the tank (with 2 snails and shrimps). He is not interested to eat while the others go at it as if they did not eat for a week. He is slower than the others. I thought the top fin or back fin may have issues as they are not as straight as the others but I don’t think there is anything there. Got them 2 weeks ago. Tank fully cycled, 0 ammonia, nitrite or nitrate, kh 4, gh 9 and ph 7.5
