My betta currently lives in a 5 gallon with some caves and a couple silk plants yet still manages to tear his fins. I'm thinking of moving him to a naturally planted tank since he's fond of laying in the broad leaves of his silk plant. I already have a light rated for growing plants, but I use gravel, would plants grow alright in it? My other question is about water changes. He gets 1 100% and 1 50% every 5 days or so since the tank isn't filtered. Would the plants be okay if I did full water changes? Thanks for any advice, I've never been known for having a green thumb so I want to do my research before I try this.
