i cleaned out my tank the other day, and woke up to find my betta hiding. i could tell he wasn't feeling well, especially with the way that he was acting. he would hide a lot. i then remembered that i forgot the de-cholorinator!!! WHOOPS... so i poured some in, and he's just lying on the bottom now (alive!)... i think that if he's made it this far, he will do fine. he looks fine on the outside. not much else i can really do... any advice, suggestions? thanks a bunch!
