Terrible tank bro there are a lot of myths of beta fish like they can live in the cup you buy them in that's fake and all lies what ever the internet says do not believe I have my beta in 5 gallons and 2.5 gallons so they feel nice

If you still have this "tank", throw it out right now and save your fish. All fish need at least 5g. Even betta's and goldfish. Those whole "betta kit!" things are just on the market and advertised as safe and a wonderful home but all those companies want is money. Get yourself at least a 5g tank. Do research on which fish can happily live in it. I suggest a 10g tank, because there's a lot more you can put in there.
Now for betta's, they need hiding places. Do not ever use plastic plants. Their fins can get caught on a sharp end and will rip, disabling them. Only use silk or live (search up best live plants for betta fish) plants. Maybe a few decorations for them to swim through, and a few moss balls (live) for them to admire and push around. Before you even put the fish in, you MUST cycle it. If you're switching from a tank under 5g to one over 5g, leave it cycle for a day or two then switch as soon as possible. But if you're switching from a 5g+ to another, then you have to let the tank go through the whole nitrogen cycle (can take at max a month). Be sure to acclimate the fish (put them in a container of whatever size and just let it float in the bigger tank for 20 minutes so they adjust to the temperature). A background is useful, so the betta fish won't see its reflection as often and will flare less. Be sure to fill it with the right amount of sand or gravel. You NEED a filter and a heater. Betta's are tropical and need water above the average room temperature, and every fish needs a filter. Now, I can't stress this enough; use a water conditioner EVERY water change to rid it of harmful chemicals. Otherwise, say goodbye to your fish. This can be bought at your local pet shop (don't trust employees, most times they have no idea what they're talking about). I suggest using an ammonia treatment once a week (follow the guidelines), getting a siphon to clean the tank and a pH test kit (be careful with this) to use once a week
