I need to set up a planted tank quickly. I'm open to any kind of suggestion

I won a live betta fish in a raffle. I don't currently have a ready-to-go aquarium available. I don't want to pass the fish on to the alternate winners because keeping bettas in proper aquariums isn't common in my country; they are usually viewed as fish for small bowls. There isn't time for a classic fishless cycle, so I plan to set up my 4-gallon tank (I hope this space doesn't feel too cramped for him/her.) using the "silent cycle" method. The API Master Test Kit isn't available in my country. I’m going to use the Tetra 7-in-1 test and the Seachem Ammonia Alert. What should I watch out for?I am open to any suggestions.

I would rather 5 gallons for a Beta but 4 gallons should suffice just fine. Make sure to have bubbles happening as they will help keep the oxygen level high by disrupting the water surface. Some floating plants are also good for this fish. Unless you want to constantly be trimming and thinning stay away from duck weed.

You can cycle with fish present but be prepared to check ammonia/nitrites daily and do a lot of water changes.

Keep your ammonia level around 0.5 PPM and the Beta should be OK and over time good bacteria will form and take out the ammonia. When you start seeing nitrate levels you will know that the bacteria that knocks out the ammonia are there. When the nitrate level drops to zero or close the tank should be cycled. Still need to do water changes at least weekly as, once the nitrites are gone,you have nitrates. While it will take longer nitrates can still kill a fish. To control this is one of the big reasons we do water changes. In a 4 gallon tank I'd suggest the water changes be around 50% weekly. Make sure to treat the new water with a water conditioner that will remove chlorine and chlorimide. Just don't use a product such as Stress Coat that includes aloe. The aloe will build up and harm the fishes' gills.

What are your water parameters? Ammonia readings can be deceptive as there are different forms. Here is a link to a calculator that will give you a good idea as to how much harmful ammonia is present. Just enter in the numbers and it will give a good idea as to harmful ammonia.
