time and they are still as good as new.i recommend to everybody to get zebra dinos!and guppys,well thats a whole new story.but when u are experienced with alot of fish(2-4 years or less of doing regular fish stuff)you can experiment with guppys.they are kinda hard to take care of,in fact my last guppy died today.but on the bright side they breed kinda fast.

Zak,
You can find tank dividers at some aquarium shops, but you are probably better off just getting a breeding, quarantine tank. Zebra’s are known for both being very hardy and easy to breed.

How long will Zebra’s carry their eggs before lay?

Nicholas,
It depends. A female will not lay her eggs until she finds a male to mate with. Once she settles on the male, she will lay them to be fertilized by the male.

Hi Thida,
Not really sure. My Zebras usually stick around the middle although many times they are just plain all over the place. They’re fun to watch. Might be feeling crowded by your other fish?
