I have two fish tanks, one is a 2.5 gallon tank and one is a 5 gallon tank. They both have one betta each. Only the 2.5 gal has a filter, which I honestly don't use very often since it has a fairly strong current. I change the water for my 2.5 gallon either 50% twice a week or 100% once a week depending on how clean it is. I just got the 5 gallon today, so I haven't done anything besides fill it up for the first time.
I have read the cycling sticky several times and I still don't really understand it. I don't want to know about the nitrogen cycle, I understand that as best as I'm going to. The scientific background info in a lot of cycling how-to's detracts from the actual "how-to" and I have trouble understanding that.
I just want to know if I have to cycle, if the tank does it on its own, and if it's bad for the fish if I don't cycle. And, if I decide to cycle, what do I need? Filter, live plants, etc. And I think the 2.5 won't cycle because it's too small? What about the 5 gal?
Besides these questions, is there anything else I need to know?
Thank you so much. I know I have a lot of questions and any info you can give me will be greatly appreciated.
