2.5 tank help!

[flame_fish]

Okay, so i'm going to get three 2.5 betta tanks for my 3 bettas. They have been in this ugly unfiltred & unheated containers. I know its bad but thats all I could have and I want to upgrade. The new tanks have heaters & filtres & I just wanted to know do I need to filtre the tanks? If so how long? I was thinking like 2 weeks? I'm not sure please help thanks!

Do you mean to cycle them? Running the filters on a tank without an ammonia source will not cycle a tank.

Yes definitely need to be cycled. All tanks do. You can do fishless or fish in. Since you already have the fish in bowls they would be better off in the tanks while doing a fish in cycle.
