hmmmm? come to think of it, he looks like the color of blue Topaz, i have a ton of names but finding the right one that represent the betta is harder than most people would think.
I've had a few people who just named the Betta, Beta LOL , i usually go by color and personality when picking fish names.
Tsunami - Bursting with color, not the actual destructive wave
Topaz - nice beautiful blue on him
Oracle - i dunno for some reason he reminds me of one of those from the Neverending Story movie, i guess because of the brightness of his colors.
