Unless your betta is ill with something you know needs treating, putting medication in the water likely isn't going to do anything, and may actually stress out your betta more. Poor Pippa doesn't look like he has much room to explore, rest or be himself! Bettas are best kept in tanks with filters and heaters just like other fish, along with plants to hide and rest on, and things to check out, rather than a bowl, and moving him to one may help keep him from getting ill or becoming too stressed. If you're worried about the water quality, you can also bring in a sample to most local pet stores to have it tested and make adjustments as needed.
