Thanks guys! I think I will do what you guys are recommending. So my setup will most likely be a 1 gallon glass bowl, bare-bottomed with java moss, a marimo ball, and two glass shrimp. Then again, marimos are really expensive at my LFS ($25 USD), so it may just be the java moss.
All my fish:
Jimmy- Dark Red and Gray Male Veiltail Betta
I'll be getting more fish soon.
My possibly-could-be stepsister's betta:
Mystery- White, Pink, and Purple Female Veiltail
