I think you have to take some factors into account, some will say yes some will say impossible, I think you would start with your tank parameters, does the temperature, the ph, the kh and even the water flow in your tank work for your betta? Then check your tank setup is there any element in your tank that can hurt your betta? After that you must have compatible tank mates and even when in theory you have right ones the tempers of each fish are different, I think that the best easy to introduce him to the tank would be using one of those breeding things that you can have inside the tank with suction cups, well all of this is just my opinion
