I have a 2.5 gal tank.
I have it all set up with my silk plants, stone substrate and a cute little hide for him. The filter in the tank right now is good for about 6 weeks(so says the package) I have it hooked up to an airpump. I had a betta in it but can not get the ammonia level down even after a water change so I put him back into his old 1 gal bowl.
Can I cycle a 2.5 gal tank like I did my 10 gal tanks? I was thinking I would get a better filter is it can be cycled and a heater too.
