IMO the best thing you could do if you'd like to get into fishkeeping would be to get/adopt a Betta fish.
Have you ever seen them in stores, living in shallow, dirty cups of water (because they must remain separated).. it's horrendous - the conditions they are kept in.
Get yourself one Betta, they don't require much work at all. Put it in a small/medium plastic tank, do manual water changes (1/2) at a time maybe only twice a week. Put beautiful plants and ornaments in the tank and feed it Betta bites or canned blood worms. Just saving one of these beautiful fish will bring you such happiness - and they will live a happy, content life, esp being taken out of the awful living conditions they are being kept in at stores, including big market stores like Walmart and Meijer.
A great place to start, easy maintenance, and the 2 of you would be so happy. A double-rescue on both parts. 🐟 💙💙
Beautiful fish, lovely long tails. They only live 2-3 years but you sure could make them happy years, for both of you. 🙂 Just a suggestion.
I've rescued so many in my lifetime... too many to count!
