Hi! I've just joined the forum, hello to all and thanks for any advice. I've got a 1 month old 10 gallon Betta tank with a banana plant, bacopa monnieri, buce mini red and a super red ludwigia - they're basically sticks and the mini buce is, well, mini, I'd like fill up my tank but I'm a beginner and I've never used CO2, and I'm not sure I want to have to...I've got a little driftwood bonsai in there too but I'd really like to fill it up. I'm also thinking of getting a snail,so I'd love some thought on those as well...thanks a lot!!
