Yea but no one answered so I just spent a few hours looking for more info. Finally decided that it can't hurt to add a bit of aq salt (as it won't kill the marimo or bamboo if it's in small amounts) and just keep an eye on him. But now to go relax and eat icecream!
I was reading something somwehere earlier about marbles and saw this setof photos where this solid turquoise bettaturned into a cambodian butterfly betta just because of the color-changing gene over time. Was nifty.
I'm kinda sad that his blue is all gone, but he's such a spunky little guy. He always jumps out of the water at my fingers if I hold them above my tank and he was playing "peek-a-boo" with me earlier xD
