wow, i feel like a new mom paranoid about everything!
there is a white thing (looks like skin?) behind my betta's chin fins (sorry, don't know the name). I don't remember it being there, but then again, I have only had him for a little over a week and have been gone for 4 days of that time. It doesn't look fuzzy... just kind of looks like skin hanging there, or a piece of fin or something. Can't tell if it is getting bigger, tho it does stick out more when he has eaten and his stomach is a little bigger than usual.
his other tank mates (2 other bettas in divided 10 gal) have no problems. i gave him a salt bath yesterday and only noticed this for the first time after the bath.
is this something i should be concerned about? keep an eye on? he has not been "itching" on anything.
