The width will limit the tank size. The largest tank would be a 25 gallon tank. If you choose this size, make sure the stand can support upwards of 300lbs. That is what the tank will weigh once filled and set up.

Hi, and thanks for your question. There is a general rule about it which is a rough estimate not to overcrowd your aquarium and avoid excessive production of feces and organic debris. The rule is one Inch per gallon, so in 10 gallons there should be ideally 10 inches of fishes in total. You should consider as well the presence of plants and gravel and any other sort of things, which decrease the water volume of 5-10% (so 10 liters are actually 9-9.5). This rule does not consider modern filtration systems. Food containers can be used effectively as hospital temporary aquarium but not for normal ones.

To safely mix fish species together, there are a few considerations to keep in mind. First, you want to choose fish that have similar temperature requirements as your betta. Otherwise the fish can be stressed. Second, you want to get species that have similar oxygen requirements - bettas don’t need a lot of bubblers in their tanks, but not all species are like that, so unless you want to do some adjustments to you betta tank, it is a good idea to get other species that don’t need a lot of oxygen. Third, it depends on how many gallons your tank is. Overcrowding is a common problem for many fish owners, and it can make it very difficult to keep up on the water quality. The general rule of thumb you can use is one square inch of fish per gallon. When using this rule, go based on the adult size of fish, because often people get fish that are young and small and don’t anticipate that they will get bigger! I would advise getting your thoughts together about the parameters above, and then vi

I would recommend to house your betta(s) in an aquarium of at least 5 gallons. 2,5 gallons could be okish, but it is always possible your Mr.Fishy will suffer from lack of space. Betta bowls are usually not suitable and appropriate for Betta fishes.
