When starting a new aquarium sometimes it is best that before you put any fish in it that you let it cycle (let the filter and other equipment run) for about a week or two. This helps the good bacteria needed for fish survival to build up so that when your fish is added it doesn't struggle with building it up himself.
Dead or dying
Betta fish may be dying due to poor water quality, improper tank conditions, or diseases. To prevent this, ensure the tank is clean, properly sized, and has a heater and filter. Regular water changes and monitoring for signs of illness can help keep your betta fish healthy.
This depends on many things like how many fish are in the tank, what is the dying fish diagnosed with and what type of fish are in the tank. If you did want to be on the safe side of your other fish i would remove the fish but unfortunately this could cause less chance of survival because moving the fish can cause stress which will sicken the fish even more so the best solution is to, remove the healthy fish(s) into adifferent area and keep the un healthy fish in the aquarium or fish tank.
