HELP...Danio

[abrar90]

One of my female giant danio ...her tail fin and lower body has turned red... is it fin rot??

I read in the danio primer...that after they have done breeding the same is to be seen... so what is it??

and she is swimming a little more fast than usual... and when she comes to the surface... she just makes her top fin splash at the water and then do normal swimming.... the other danios (all of them try to run after her.. when she passes them by)

I have shifted her to another tank.. and she is alone there.

Cant really make anything out in the video however it is normal for a giant danio to have red in them- it is not a bad sign at all.

Appears it was a secondary bacterial infection. Also looks to have had fin rot.
I'm sorry to hear about your fish.
