I want to get a 5 gallon tank for a Betta, and use live plants. I also want to start replacing the fake plants in my 10g with live ones to help with my nitrates. I want to use a few varieties of Java Fern and maybe some Java Moss in the 5g. Anyway, I'm not really planning on fertilising the plants or anything...so, first of all, could I get away with that? And if I can, I'm worried that a single Betta would not produce enough CO2 and Ni3 to support a bunch of plants. In that case, I'm just as open to getting a couple of females. Just some general advise on plant keeping would help, or ideas of other easy plants that don't need good lighting. Thanks for any help...I've got the fish down, so step two is the plants!
