Well, from your picture in the other thread, Lupes has stated in is a Male Betta Splendens. Most common type available.
Now, you need a few things in your "bowl." You need a heater, and a filter helps a ton. If no filter, then you need to water changes every day-every 3 days (depending how big it is) to keep the params in line. You also need plants (real or silk work best) and hiding spots for the betta.
