Team Zebra...at the bottom now?

[ryanjcalifornia]

I wonder if this has something to do with my betta who always swims at the top, but,

I have a 10 gallon tank, and when i first got my zebra danios they swam happily near the top with the betta, and everything was great and fantastic.

Things are still great, but now they're happily swimming on the bottom of the tank, this time with the cories, they don't go up to the top any more, except for feeding...

I dont know if they dont like they betta, or they need to change it up, or if the leader zebra just decided that it was time to swim on the bottom, or maybe they just dig the cories' personalities!

Your thoughts? Opinions? Experiences?

Thanks!

When I first got them, they used to swim around in the bottom at the back right corner. About a week later, they were at the top. Then after about 3 weeks they go everywhere.
