Here's my male crowntail Betta "Wallace" aka Wallie in his 1.5 gallon. I modified the airtube to the corner, changed out my gravel from red to a more natural white, and added some slate pieces. I also made the custom grass plants and modified the sword a little bit. Water is a little green from some Fungus Clear I added. I'm upgrading him to a 6g eclipse in a few weeks. I'll post pics when everything is up a running.
