Symptoms and Treatment
How has your betta fish's appearance changed? Earlier, he had some weird milky white iridescent strands flowing off of his caudal fin. They looked a bit like spider webs. But when he swims quickly, they fell off and were just floating suspended in the water column. I've attached pictures of the strands floating. They are no longer on his caudal fin from what I can see. He has new growth on his caudal fin, both the rays and the parts in between them. I thought he had a white spot on the frontmost part of both his dorsal and anal fins, but as I looked closer for longer, I realized the white spot on his dorsal was clear and had a new ray coming out of it. Do crowntails grow new rays? The "white" spot on his anal fin upon further inspection was turquoise and iridescent, so I think it's his coloring becoming brighter. He also has a tiny turquoise spot on his right pectoral that I originally thought was white. Do their pectorals change color too?
How has your betta fish's behavior changed? It hasn't. He's very active and likes to be a little piggy at feeding time
When did you start noticing the symptoms? 30 minutes ago.
Have you started treating your fish? If so, how? No
Does your fish have any history of being ill? Not that I know of.
How old is your fish (approximately)? I just bought him on Sunday.
The floating strands are next to the reflection of my cell phone camera's lens in the first picture and in the middle of the second picture.
