Exclamation Neon Tetra darting at each other?

I'm currently watching my 5 neon tetras behave how I've never seen them before? They're relentlessly chasing each other - looks like 3 males are fighting over the (what I assume are) females? I normally have a peaceful tank and now I have tetra frantically 'tagging' for each other..

On another note, would anyone be able to tell me how to sex Neon tetras? I'm judging my guess on the colour of their blue stripe, 3 have dark ocean blue stripes with blood red tails whilst 2 have the typical teal and light red colour?

Hello,

1. Check that your tank is enough spacious, neon tetras should ideally have a 80cm long tank, they need swimming space, despite being small, they grow 5cm tall. Something which is often overlook, because they look small.

2. Adding more will probably help they need to be in good numbers, aggressiveness will dilute in a schoal of 10 or more, if they have enough space.
