Yea the blue scales on top of the black ( it doesn't picture well ) mixed with the red shadow is the whole reason I got this one. He was by far the best looking betta in the store.
I dont have a clue, he was all alone in his dinky little cup that they keep them in. is grown already so im not to worried about it. Im more worried about his color fluctuation. in my first pics he is almost black and in these ones he is alot brighter and almost all red, but the other day he was blue like all blue... he is like a chameleon!!!!
Good looking fellow.
Have a similar CT. But not nearly the blue, just a sheen.
Depending on his personality, it may be a one fish tank. Mine is in a 10gal. and he is High lord and master of his tank.
