Hi and welcome!
Guide to Starting a Freshwater Aquarium
Here is some info for beginners.
I'm just going to point out some thing out for you.
Bettas are like any other tropical fish. They require a heated, cycled (refer to link) tank with a filter to thrive. The bare minimum is a2.5g tank but 5g is preferred.
Goldfish are messy creatures and require large, heavily filtered tanks. Pond fish (koi, commons, comets, shubunkin, most feeders) require large (125g+) tanks but ponds are more appropriate. Fancy goldfish require 20g for the first fish and 10g for each fish after that. So if you have 3 fancies you need a 40g tank. Because they are heavy waste producers they need filtration 10x the tanks volume. So a 40g tank needs 400g per hour of filtration.
Mollies require a 20g tank and neon tetras need schools of their own kind of 6+.
