Bettafanatic
Aquarium Advice Addict
I started cycling a couple of 2.5 gallon tanks for my bettas. They're beginning to get really upset, especially the male. They are both growing less active and I'm worrying about them. My friend has a betta in a 2.5 without a filter. She didn't cycle it and everything is fine. I was wondering if I can just kill all the ammonia, remove the filters, and skip cycling. I don't necessarily have to; just wondering. If I do so, will it start fish cycling? My friend hasn't seen any nitrites or anything. I hear you can't cycle without a filter too, so I thought it wouldn't. Thanks!
