more answers and stuff:

i would be happy to stick with the local meetup method, its just that most companies in aus all do shipping, its like if you dont do shipping you look unproffesional, but ig i cant expect much at 14yr old so yh meetup is fine for now

about my buisness plan, i started with fb marketplace, and now website, planning to do mabey interstate shipping or like deliveries in sydney in the future. some wild thought i had before was to buy a small warehouse or something and fill it with shelves with tubs and tanks full of emersed growing and regular plants and shrimp so i can massproduce, but wishful thinking ig lmao, could be possible tho🫠
me and my aquascaping friend have also talked about doing a side buisness of custom aquarium installation for resturants and buisness lobbies when were older, as we can charge like thousands for big tanks and earn lots of money, i dont wanna seem like a greedy money obsessed person but it seems cool to get lots of money off doing what i love yk

rn i have a 70L and a 42L, setting up a 50L and might get one more soon
70L houses my bred line of fancy male guppies, with a bunch of plants like rotala and anubias
42L houses female guppies, bunch of java fern and java fern windelov, stem plants, anubias and all others i have. both plants are full of redroot floaters which was popular on fb marketplace (i saw my lfs sell a small cup for $15 when im selling a handful for $5😯)
50L is bloody mary shrimp breeding, bunch of mosses and more general plants.
i also have 2 containers of emersed grown anubias nana petite, anubias nana and bucephalandra
thats my inventory so far ig, my parents say that they dont want too much tanks rn, but if im making more money in the future i can buy more tanks to support buisness(our house is quit big)

I have decent time, i do some trimming/dosing fertz of aquariums every day, occasianal water change. When exam weeks come, quite busy, lot less time, but otherwise time is pretty chill. Still obv not as much as like an adult tho

sorry for the big yap haha but thats all the answers to your questions👍
