I just set up a little 5 gallon planted tank. No fish. I was wondering if I can do a fishless cycle, will it hurt the plants. Or am i better off putting betta in there.
the plants will be fine altho if your only wanting a betta in there then theres no need to do the cycle.
well, unless its filtered i guess but most peoples betta tanks arent and they jus do 100% water changes every week so thats not cycled when they put the betta back in.
jus make sure you treat the water and get the temp right.
