Yes, this is fine for a Betta tank. You should still use a small filter as well as a small submersible heater to maintain water temp. Bettas do best between 78 F and 80 F. If you choose to use tap water, use an appropriate water condition to remove harmful chemicals and heavy metals.

Maintain pristine water quality via filtration and regular partial water changes. Use only conditioned water that is temperature matched to prevent further stress or shock. Bettas do best between 78 F and 80 F. You can try an "all in one" product, such as Lifeguard by Tetra, to treat the condition. Find it in the local Petco or online. Follow label directions carefully and remove the carbon filter insert if indicated. https://www.petco.com/shop/en/petcostore/product/tetra-lifeguard-all-in-one-freshwater-aquarium-treatment

A fish tank will need a filter, a light/hood and a heater. Make sure the filter is rated for at least twice the tank volume. The heater should be adjustable since water temperature will depend on the species of fish. Good "starter" fish include Tetras, Mollies, Danios or Tetras. A new tank should be set up and left running empty for several weeks before adding fish. A pinch of flake food can be sprinkled in daily. This "cycling" will allow a population of beneficial bacteria to colonize the tank and filter. These bacteria will break down wastes (ammonia, nitrites and nitrates) which are toxic to fish.

The bowl looks definitively a bit small for the two fishes. To understand exactly what is going on you need to approach this problem radically but logically. Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. Clinical examination should always include a water quality check, even if you have done so already. Water testing should be performed with a quality test kit, measuring NH4, NO2 and NO3. High ammonia levels, PH imbalances may be responsible for these signs. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, your fish should get examined to look for any sign of bacterial/fungal infection and eventually water should be treated.
