Welcome.
This place is probably the best place on tinternet for beginners. Most forums seem populated with a few who have forgotten they were beginners once too.
Take your time and get your tank cycled properly, whichever method you choose.
Buy the two testing kits mentioned above.
Ask questions on here. Donāt be embarrassed no matter how trivial or weird you think your question may be perceived as.
Look at fish videos on you tube. Itās a window on the world of fishkeeping. Thereāll be hundreds of fish you like and dozens you love. Not all will suit your circumstances.
Check your possible fish choices on seriouslyfish.com as mentioned above with your circumstances IE (tank size, water temperature, ph, water hardness, filtration, water flow, fish size, feeding, breeding, substrate, plants, plant density, tank mates etc).
Ask on here if youāre choices āworkā. SF canāt cover everything and as theres hundreds of years of collective experience offered daily on here free of charge youād be a fool not too....and anyway that positions already taken
Dig around on here using the search facility for your possible choices also as theres something like 20yrs worth of questions, arguments, answers, mistakes, solutions etc in the back pages.
......and almost finally donāt take the word of anyone trying to sell you fish or fish related stuff as gospel. Always check on SF or here and you wonāt go too far wrong.
......and finally. Get some Corys and Microdevario KubotaI and at least one Banana Plant if youāre parameters allow it....I mean why wouldnāt you?
Have fun, have fins, stay safe.
