Is My Zebra Danio Pregnant?

[alisonarty]

Hello all, I am new to this site today. I am worried about my Zebra Danio. I had only one in the tank and last week bought another one, I don't know the sex of either of them. The new one chases the old one around but they seem happy together. Over the last few days the old Danio has got fat and around his?her bottom are looks pink, scales are fine. Do you think it is pregnant.
How do I know if this fish is male or female.
I have sent a picture as an attatchment
Thank you for your help.
Alison

Over the last few days the old Danio has got fat and around his?her bottom are looks pink, scales are fine. Do you think it is pregnant.

a fat ZD with a redened anus does point to the fact that she is full of eggs.
as they are egg scatterers they do not get pregnant but egg-laden.

if you wish to try and breed them checkout my website and go to th sexing breeding page.

If the fish is bloated and has a red anus it's pointing to a bacterial infection, they can get a red anus with dropsy.

Or yes it could be she full of eggs.
