wow, he's gorgeous!
walnut has started changing colors recently as well. his fins are going from dark to light blue. it kind of freaked me out at first, but now i think it's kind of cool!
well, when he got the green, i wasn't too surprised, but my husband turned all the lights off in our bedroom (where his tank is) and left his tank light on... after flaring for who knows how many hrs at his reflection, i was worried the color change was from stress... apparently not
he eats hikari betta bio gold pellets. and every once and a while a few bloodworms- but he gorges himself on those, so they are a rare treat followed by a day long fast.
