This is a photo I just recenly took of my new Halfmoon Betta, Tsukasa. He's quite the willy one too! I picked him up from Petco having originally gone in to just get some frozen bloodworms for my Delta Tail Betta, Shibuya. The one thing I find interesting is the size difference between him and Shibuya, but I guess that's just cause Shibu's much older.
He's currently in a one gallon decorative tank until I can get another 2.5 gallon tank like the one Shibu is in. I know the tank is small, but for now it seems a comfortable size considering he's rather tiny. (I always move them up to bigger tanks)
