my betta isn't showing any symptoms of ANYTHING with the exception of him being extremely lethargic and lacking an appetite. he hides at the bottom, only coming up for air every once in a while.
he's in a 10gal with a filter and an airstone. nothing has changed in his tank in MONTHS. he used to eat and eat and would probably have eaten anything in sight had i provided it. now he might try a piece or two, sometimes spitting it back out.
no flashing. nothing on him that i can physically see. no bloating. no fin rot. :/ i've been doing larger water changes since he started acting differently. it's been a couple of days. i'm headed to the store to get more aquarium salt now...
