Symptoms and Treatment
How has your betta fish's appearance changed? He's a lot paler, begun either tailbiting or he blew his tail.
How has your betta fish's behavior changed? He picks at his gravel a lot, even though there's nothing there. He also likes to sit at the bottom with his body tilted up.
When did you start noticing the symptoms? Blown tail and gravel-picking on the 29th, when I got back from vacation. He's gotten worse since and begun sitting around.
Have you started treating your fish? If so, how? Haven't, although his water is clean.
Does your fish have any history of being ill? Absolutely none.
How old is your fish (approximately)? Got him from Petco in early March, so about 9-12 months?
Yeah, Midnight hasn't been feeling well. I can't put my finger on it, but he seems kinda sickly. Maybe it's just finrot, but I don't know if that also makes them listless. Pictures coming momentarily.
The red stripe along his side is the lighting or something; he doesn't have it IRL.
This basically shows the rips in his tail. I think I might start him on AQ salt, because his fins are so dark it's hard to see any black edging.
