That's great that you were able to find a home for the other fish! The rams should be very rewarding to keep! as @ClownLurch said, it can be overwhelming at first with all the information that is being thrown at you, but you are doing great so far!
To try and consolidate some of the information you are getting, here are some steps you could take now to ensure that the next week or so in your aquarium keeping life goes well:
1) find out the water parameters of your tap water, as well as the water parameters inside the fish tank. One way to do this is to take two samples (one from your tap, and one from inside the tank) to a local fish store, and ask them to test them for you (as @essjay said ask for the numbers, not just whether it's "ok" or not), write down the numbers for both samples and post them here. You can also purchase a water test kit and test the parameters yourself, if you choose to go that route you should get a kit that test for ammonia, nitrite, nitrate, KH, GH and pH. One popular bundle to get all of these tested is the API Master Test Kit + API KH and GH test kit.
2) once you have the water information, we will be able to advise you how to do water changes on your tank. Do you have the equipment to do a water change? For a small tank like yours, you will need a bucket and a gravel vacuum. You do not need dechlorinator if you are on well water which is untreated. The way to do a water change (sorry if you already know this, I am assuming no prior knowledge and trying to help) is to set up the bucket on the floor (have some towels handy for drips as well), start a siphon in the gravel vacuum, vacuum the bottom of the tank until all the poop and gunk gets sucked into the bucket (swirling the vacuum helps), and then watching your water level on the tank until you are down 20-50%, and then taking the gravel vacuum out. Open up the filter, take out the filter pad, and swish it around in the bucket of water so that most of the "gunk" comes off the pad. put the pad back into the filter. Dump the dirty water from your bucket down the toilet, wash out your bucket with clean tap water ONLY, and then fill up the same amount of water in your bucket that you took out from the tank from the cold water tap. Use a kettle to heat up water, and mix enough hot water into the bucket to be at the same temperature as the tank water, and then pour the water back into the tank. It is easiest to use a bowl or colander to catch the water in the tank so that you don't make a giant hole in your gravel and stir up a bunch of muck. Then, turn on your filter and heater (sorry I forgot to mention that you turn both of these off during the water change - easiest is just to unplug them), and keep an eye on your fish to see how they are doing.
3) Once we get the water topic figured out and get you on a routine with water changes, you should start looking into a larger tank. There are multiple benefits of a larger tank, notably that the water parameters stay more stable and you are less likely to have a "crash" in your fish tank (this is a situation where something goes wrong with the water and everything dies, don't worry, it doesn't happen often but it is more likely in a smaller tank). Another big benefit of a larger tank is that you get to keep more fish! And that is a reward in and of itself
I would recommend to go as big as your budget allows, and definitely try to buy things used! At least in my area, aquariums hold no value for resale, so you should be able to get a relatively new aquarium in good condition for about 50% of what it costs new in the store. Your area may be different on how much the prices are reduced, but checking local classifieds will hopefully net you something that is a great deal! This topic may be helpful for you in determining whether a used aquarium is worth buying: https://www.fishforums.net/threads/buying-potentially-ancient-tank-no-known-history.465090/
There are a bunch of other (more fun) things you can also work on during and after these steps (like aquascaping, and getting plants, etc!), but best to focus on the most important aspects to start with, and then get to the fun stuff after that
Keep us posted about the water information!
