Maybe you could start with some home stuff. Try to grow out some frags to sell, maybe breed something. Try and get an idea of local demand. Consider working at a LFS that you don't own.

Now that makes sense!The best LFS I've ever been to started out in a small garden shed, moved to his garage and then built a huge shed in his back garden. It's extremely successful and as his business grew so did the footprint of his store which is a few steps away from his house.
I worked at my LFS for a few years and I already own a dog grooming business so I feel quite preparedI would suggest working at a LFS for awhile first. Really understand the business side of things. Then once you have a good grasp on the business side of things you would be better suited to start your own LFS.

Aquarium store. Salt, Freshwater & Cold! Obviously as well as selling equipmentDo you want a aquarium store or a pet store. 2 different animals.
I would also set up a big online store! And maybe branch into selling things for birds too as that’s lacking in my area and I love them to bits!I appreciate the advice. I only said no negativity because some people can be plain cruel rather than constructive. I live in an area with very high demand so I do think I could do it.I have owned an aquarium store. I started my store on 9/1/2001.
I failed ... miserably.
If this is the way that you look at this then I highly recommend that you avoid taking up this idea.
I thought the way that many here think about this and it cost me $100k, bankruptcy and years of deprivation dealing with the aftermath of what I had done.
Business isn't something to be messed with. Asking people on a message board about something so difficult and personal is a sure sign that you aren't ready and you don't get what will need to be done.
Sorry if you see this as negative, but it is the truth. Maybe you will not do what I did and save yourself the pain and the suffering of being ill prepared for what is necessary.
Be happy with your path and follow it to your ability.
Good adviceI started one in a spare bedroom of my house a number of years ago. Got the wholesale accounts and everything. It was fun for a while, but eventually got old having people come over every night after work. I would start that way if you can. Good way to judge demand And build a customer base without shelling out much money.

I have 10 years experience with freshwater and cold water as well as Marine so I feel comfortable with it.My first actual experience with a LFS was as a child/teen in the 80s. The owners wife was friends with my mom and I went to school with his daughters. I saw that store go into business from r ground up. I hung out there every single day after school and all summer. Unfortunately there is no useful business data as he was a drug dealer and the store was a front to launder the money (I swear I'm not making this up. Drug dealers love aquariums). He's long passed (from old age not consequences of the drug trade) so I feel okay sharing.
I did some close observation on two local reef shops that went from basically home based operations to real stores and in both cases the owners basically LIVED in the store (not metaphorically, a back room where they could sleep) with mostly family members operating the store. All their progress was publicly documented on social media and reef club websites before they even opened publicly. There is ALWAYS somebody in there doing some sort of maintenance on the aquariums and equipment. Neither did anything else but reef/marine (do you really want to learn/deal with the freshwater market with a zillion categories, people trying to return feeder fish, reptiles, cat/dog supplies etc or hire/partner with somebody who does. We have a lot of LFS and NONE are good at saltwater but only a few reef stores which are superb). They were both aquaculturers as much as they were retailers (but vput the grow out somewhere besides the showroom. One of these guys in question really got on my nerves when I'd pick out a coral I wanted to buy only to hear "it's not for sale, I'm growing it out a little more first". EVERYTHING in the showroom should be for sale!
Sandy's?Great input here. The one LFS in my area that has been around many years does everything Freshwater , saltwater, dogs, cats, birds, rabbits, ferrets, dry goods, equipment, maintenance. Longevity has to be based on covering a broad spectrum of hobbyist to survive long term imo. All SW only stores in my area last about 3 to 5 yrs and the next guy opens up...wash/repeat
