I'm planning a 500-600 gallon planted non aggressive community tank. Hopefully, it will be built and started within the next year. I don't have much experience with aquarium plants so I need them to be low maintenance and, hopefully, without CO2 or super overpowered lighting. Stocking is still up in the air right now. I know I'm going to put some type of shrimp and snails so that I can hopefully have a breeding colony of both as food for a separate pea puffer tank. Any planting suggestions would be much appreciated. I've never planned out a tank this size.
