I've been treating my betta for fin rot with antibiotics for about 5 days now, and he's starting to become himself again (more active, no signs of rot on fins anymore). He's been moved out of his 10 gallon tank into a 2.5 gallon hospital tank since treatment, although there are no signs of rotting on his fins anymore, they are still not fully grown back.
When should I move him back into his 10 gallon, and when should I stop using the antibiotics and start focusing on regrowing his fins?(or will the antibiotics continue to do that?)
Thank you so much.
