One this is not going to be cheap at all! I have a few friends who have started there planted aquariums and they have a 20 gallon and a 30 gallon tall tank and the friend Witt the 20 has spent well over $350 on there's and the other has spent well over $500 on there's. You will need a CO2 system, a high lighting system (depending on the plants you want), and various chemicals and soil to even get started. For you stock you can have anything that moves slowly or is not a big fish, for example discus may get big but the are peaceful slow moving fish, or you could go with tetras and shrimp or you could go with both. You would not want any cichlids that move around to much and get to big, this will mess up your landscape and most likely tare it up. My suggestion is do more research on the subject and find out what stock you want, then start saving and planning.
