For anyone who doesn't know, I am running a betta rescue - people can drop off sick or unwanted bettas with me to care for. Today for the first time, I got a girl! I am wondering if she is a marble? I am also wondering if you think the purple on her fin is her coloring or some kind of ammonia damage?
She was in hardly any water when I found her about 20 mins ago, I added a little so she could swim. She's pale. I immediately went to goodwill to look for a tank or suitably large vase or something and found a 1 gal drum bowl, so she'll be living there. I'll post photos of her tank set up when I come back from this job interview later! Wish her luck <3
