I just rescued a betta from my friend's sister. It has the beginning stages of dropsy and about 1" of brown water in a half gallon bowl. I did a small water change and added a bit more water so he had more swimming room, but the smell is just awful :yuck:. I don't want to shock him, but I really need to get that bowl clean. How often should I do water changes until it's cleaner? Hardly any of the stuff in the bowl is fish-safe, but I took a little bit out because I didn't think I should take it all out at once. I'm not sure if he'll pull through or not but if there's anything I can do I want to help him. I want to move him to my 10g soon as well. :help2: Thanks!
