Symptoms and Treatment
How has your betta fish's appearance changed? Fins even more ripped :C
How has your betta fish's behavior changed? Hasn't, I think I have 2 retarded bettas now...
When did you start noticing the symptoms? I thought she got slightly nibbed 2 days ago but I didn't check much, yesterday was my bday and I haven't been around to check the aquarium... When I checked she was beat up so I quickly removed her from the tank :P
Have you started treating your fish? If so, how? Yeah, salt treatment for wounds 1tsp/g
Does your fish have any history of being ill? Huh.. I think 1 week ago when I went to my LFS she was one of the fishes that most died from illnesses and the others had fin rot (from 10-15 bettas only 2 survived) :P
How old is your fish (approximately)? No idea, I would say from 1.5month to 3 months old (I have her for 4 days now)
I don't know if this is possible but I think this poor female is being "bullied" or picked up from the other females, I mean, the aquarium is peaceful now, the others aren't biting eachother, just this one here... I don't know why :C
She came in with something weird on her eye, but with 2 days on the aquarium she recovered from whatever it was... Now her fins are all ripped, even more than it was when I got her and she is missing one of the ventrals.. I think if I didn't remove her yesterday maaybe she would have become a fish-food for the others... Kinda like what happened to Burd's sonority.
PS: I know you will say 2.5g per betta, but the last 3 females on the petshop were on the same tank as a male, who were attacking them, and my LFS wouldn't change him.. So I got the last female which is a dwarf :P.
