Symptoms and Treatment
How has your betta fish's appearance changed? well she did colour up slightly since i got her home. plus she's developed more black spots on her sides and i'm not sure if that's her natural colour or something else. Also, yesterday she was opening out her fins and swimming around, today her fins seem either clamped, well more so than the last few days.
How has your betta fish's behavior changed? She's very sluggish and is just drifting around the tank. yesterday she was full of energy and exploring, now she's become a little obsessed with the thermometer and is floating by it like it's her saviour.
When did you start noticing the symptoms? this afternoon.
Have you started treating your fish? If so, how? no.
Does your fish have any history of being ill? just got her so i don't really know.
How old is your fish (approximately)? she's very tiny so i'm guessing she's not very old.
I hope i'm just being overly cautious asking for help.
