@Guppysnail I will 100% post pictures, I'm just trying to get the lights and a lid all set up because I want to transfer my fish over to a new bigger tank. The lights and the timer are here but the lid might take a while. If any of you guys have any suggestions on how to move over my betta safely that would be greatly appreciated! Sorry for responding late I was busy with work and school :')

So I'm a beginner to fish keeping and I would like to know how many plants I should buy? I have a single betta but I plan on getting one snail and I'm wondering how many plants can I get out of one pot? Maybe that isn't the right way to word it, but how do I know how big it'll be and if I need more? Is it better to get a few and start small then add on? Most of the plants I'm thinking of getting aren't really root plants (anubias, frogbit, java fern, etc) and I would like to know if I can plant them in substrate or should I get a different plant for that? I know anubias can be tied to rocks and java fern can be attached to drift wood that but I was also thinking of plants to put in the substrate (maybe water sprites and dwarf sagittaria). I would love to hear other suggestions because I can't seem to find much info online. The tank I have is 5 and a half gallons with gravel on the bottom and sand on the top for substrate. I'm not 100% sure where to get some of the plants because I plan to get most of them from aquarium co-op but they don't have all of the plants I'm looking for. I can get some plants from big chain and small pet stores (I went to check the small store selections and they didn't have much). Sorry for the long paragraph, hopefully that made sense :')
