I went back to Petsmart today because my betta has fin rot. It was ok for a few days and now it's gotten worse. He still has most of his tail fin left but it's split about halfway into his tail (and frayed). I was giving him salt baths (not every day) and using bettafix but it didn't seem to be working well enough. So I went back to get medication.
An employee walked by and asked me if I needed help. I told him what's happening and asked him what I should do. These are the things he told me:
1. I shouldn't feed him pellets because they're harder to digest. Stick to bloodworms while he's sick. - Really???
2. I was going to buy Jungle fungus clear(?) but he talked me out of it because he was concerned that I will cause an overdose. I guess he's not entirely wrong because the dose is for 10 gallons and a beginner like myself could easily screw it up.
3. it's better to stick to salt baths. Didn't tell me exactly how, but he said to go ahead and put a teaspoon of salt into the small bowl I'm using while he's sick (holds about 1 1/2 pint of water) and told me to change the water every day. Sounds about right, but a teaspoon?
How does this sound to you guys??
Also, I'm having trouble keeping the small bowl warm. This might be why he's not getting much better. How do I go about keeping the water warm for him?
