Around 2 weeks ago, my betta Gibbs developed some black blotches on the edge of his fins. At first I didn't think much of it because the trimming of his fins are naturally translucent black, but seven days later, the edge of his top caudal (he's a double tail) started to look slightly shredded. Right now, his dorsal fin has a dip in it and the rot has progressed from his top caudal to his bottom caudal. The rot progresses little by little everyday and the salt treatment doesn't seem to be slowing it down. I started using Tetracycline two days ago so I'm not sure if that's helping yet.
What size is your tank? 2.5 Gallons
What temperature is your tank? 74-75 degrees (It used to be 80 but I was an idiot and broke the heater...)
Does your tank have a filter? No
Does your tank have an air stone or other type of aeration? No
Is your tank heated? No, unless a temporary desk lamp counts.
What tank mates does your betta fish live with? None
What type of food do you feed your betta fish? Flakes and dried blood worms, peas once a week.
How often do you feed your betta fish? Once a day, fast one day a week.
How often do you perform a water change? Before the sickness, 50% every three days. Now I change everyday.
What percentage of the water do you change when you perform a water change? Used to be 50-75%, now it's 90-100%
What type of additives do you add to the water when you perform a water change? Splendid Betta Complete Water Conditioner
Have you tested your water? If so, what are the following parameters? I had Petco test my water. They didn't give me any specific levels, but they said the water was nice. I did use a pool strip to test a sample though.
Symptoms and Treatment
How has your betta fish's appearance changed? Tail fins are deteriorating bit by bit each day. I haven't been able to find any pieces of fin on the bare-bottom though.
How has your betta fish's behavior changed? Was skittish earlier, but he's normal now. He still bites me when I get close enough ;P
When did you start noticing the symptoms? A little over a week ago.
Have you started treating your fish? If so, how? Yes, last Tuesday with 1tsp/gal of salt. I upped it to 1.5 tsp/gal of salt today and I plan to do 2 tsp/gal of salt with tomorrow's water change. I also added Maracyn-TC (Tetracycline) to the salt treatment two days ago. Today is the third day of treatment with the medicine.
Does your fish have any history of being ill? No, but I've only had him for a month.
How old is your fish (approximately)? A little under your typical pet store fish age? His body is only about 1.5 inches long.
If I progress with my current treatment, when should I begin to see results? :( Does fin rot normally progress with treatment before stopping and getting better? Right now I have no more money for meds and I'm worried that I won't be able to cure something as simple as fin rot.
