Zebra Danios Acting Strangely

[snakequeen]

Hi all.
I have just been watching my community tank and was in perticular watching my danios.
I have 3 altogether, 2 that are very fat and another that is thinnner so im guessing that they are 2 female and 1 male?
Anyway, the thinner one is chasing the other 2, they are going round in circles and then darting around.
I know they dart about anyway but is the circling thing normal?
Are they fighting or what?
Not seen them do it before today so was wondering if this is normal?
Thanks
Eve

It just sounds like they are breeding. The male is the slimmer one and will probably chase the fatter ones around. They might zip into some plants for a few seconds where they will lay eggs. It is quite a common occurrence in a fish tank.
