believe it or not, fish is the least important thing in a planted tank. judging from ur answer above, i think u still have lots of homework to do.

aquarium - self explanatory...
filter - it will be better if you have a cannister as it provides spacce for good bacteria to grow...
lighting - not the normal cheap lighting u can just buy at any local fish shop. must be high voltage so that the light can reach until the bottom of the tank. also depends how deep is ur water in the tank.
sand - not just any sand, most of us here use ADA soil for the tanks but heard others using JBL as well.
plants - try to do some research and start with low maintenance plants.
5 elements - Penac P, Penac W, Clear Super, Tourmaline, Bacter 100 ( this helps grows bacteria to grow in ur tank and decompose harmful material such as ammonia and nitrite to harmless materials. they also helps the growth of plants and provide supplememnts for the plants...
Co2( very important) plants will need co2/carbon dioxide and light for the photosystesis process.
diffuser - to diffuse ur co2 bubbles so that the co2 will melt in ur water rather than floating to the top and wasted.

also, search up the meaning and ways of cycling a tank.

hope i din miss out any important things here...
ps: anything u dunno, try google search or youtube it. thats how i learn most of the time...
pss: 6 months of planning is better than 6 months of headache and regretting... do sufficient homework before you start anything...
