Symptoms and Treatment
How has your betta fish's appearance changed? A couple of weeks ago, my betta's tail and fins began to show signs of fin rot. It was a mild case, but I was nervous and put him on tetracycline. I followed directions, treating two days with no water change, then a water change before the third and a water change before the fifth. After that, I changed 50% of his water each day before the 6-10 doses. At first the condition seemed to worsen. Around days 6 and 7 the progression seemed to halt and during the last few days I've seen regrowth. But when I checked on him this morning he had popeye! His eyes aren't cloudy, but they are distended (equally on both sides).
How has your betta fish's behavior changed? Not at all. He's very active, follows my hand when I'm cleaning the aquarium and jumps out of the water if I hold my hand above the tank too long.
When did you start noticing the symptoms? Fin rot a couple of weeks ago; bulging eyes today
Have you started treating your fish? If so, how? Yes; he has been on tetracycline for 10 days. I am out now, but I think he needs a break anyway. Do I give him a week off and start up again? If so, should I start Tetracycline or another antibiotic?
Does your fish have any history of being ill? Not until the past month
How old is your fish (approximately)? About a year? (I have only had him since February, and he was not fully grown when I purchased him.)
