I really don't think you should be putting tea in there unless it's "tea" made from boiled oak or Indian Almond Leaves.
Regular tea has caffeine, pesticides, and multiple fertilizers in it. Most modern pesticides and fertilizers are made using petrol (Oil, like crude oil, except of course it was refined and chemically altered for its purpose) as a main or key ingredient (trust me I'm an environmental studies major. :]).
Basically it's cool for you (just barely) but not your buddy that's about one 40th your size and doesn't have the room or the power to process all those complex chemicals and toxins that are meant for things about half his size.
I'd take the tea bag out and do a 25% or 50% water change asap.
If you live near the woods or a nature trail I advise looking for an oak tree and writing that down so you can collect leaves from it next fall. =]
For now though if you want to use a tea I'd order some Indian Almond leaves off of e-bay or something then rinse them, break them into little pieces, then boiling them in a medium pot of water. This will make a concentrated "Tea" that is safe to use for your betta. =]
I'd also try e-bay or aquabid for peat moss and drift wood. Make sure it's unfertilized peat moss though. =].
As for the video:
