Welcome Callie, To the Forum!!! I've been lurking too, before I joined. :D
By the way, I love his name, Alpheios.
You did a good job!!! Researching before buying. What size is his tank? I'm sorry if I'm intruding but, Anything under 2.5 gallons will make them not thrive. They could live but not thrive. Oh, and another one would be a heater. they are Tropical Fish. They are lethargic in cold water. Anything under 72F= Unhealthy Fish. Anyways, Good Luck, and enjoy the world of Betta Fish and their keeping!
