I compiled these photos of my husband's betta (recently passed), Sushi.
At first we thought he was sick, and everyone here suggested it was a bacterial infection. Little by little the white spread for weeks and no medicines helped.
Then after a few weeks... our once royal blue crown tail was pure white. I decided that I had to take lots of pictures or no one would believe me how severely his "bacterial infection" had spread...
Then he got red on his back... then started turning black too!? Where upon my friend, who works in an aquarium, exclaimed "huh... looks like a marble fish". Marble, huh? MARBLE!? Yep... marble. He was never ill. He was just... different
Unfortunately, he died a few weeks ago and we don't know why. He was in the bottom corner of his tank with his gill plates closed and mouth wide open. Half of his dorsal fin was missing (he was fine the night before, we woke up and found him like that). I suspect the ghost shrimp decided to munch on him during the night after he died? I can't imagine a ghost shrimp could kill a betta just by biting the dorsal fin. The parameters were fine, and no other signs of what could have done him in
Oh yeah, and funny enough... he got to be an Egyptian flag fish for a while! (ok, he could pass for yemen, seria, and iraq too... but I like Egypt! hehe)
So anyway... here's his extreme makeover, fishy edition!
