For the past 3 days or so I've noticed a slight white edge on the tail of my male delta tail betta, and I thought it might be the beginning of fin rot. I change 40% of the water every 2 days since the tank is still cycling. Sadly I had to fish-in cycle. I condition water with Prime. I figured that as long as I kept the water clean, he'd be fine. 30 minutes ago, his tail still had the white edge but it did not seem to have progressed much. Just now, I looked at him and his tail was shredded! The part where his tail is shredded looks brown-ish as if it's actually decomposing. Is this fin rot? How can I stop this rapid progression?
Sorry my photos are unclear :/ In the first photo you can kind of see how part of his tail is browner than the rest. In the second you can see the white part. In the third I'm hoping you can see the shredded part.
Heated at 80F
In process of cycling
It does seem like fin rot.
Keep up with the water changes. Good water quality is the number one and best cure.
What are the current water parameters? You may need to do some daily water changes if they are not under control.
You can use aquarium salt. 1TBS per 5g.. or 2 for your tank. Build up to that. ( that's about 3tsps. per 5g )
I would do 1TBS to begin. Make up water change water, condition it as usual. In a separate cup of warm to hot tap water, dissolve aquarium salt. You will need to mix it well, it doesn't dissolve easily. Pour the dose in your water change water and let that sit a moment. Stir it well and add it cup by cup. You don't want to dump salt water into his home.. this will be a new thing for him. Go slow.
If all goes well, you can dose again the following day. After that only dose the water you add back until the treatment is over. You can remove it with water changes.
Thanks for the reply! Unfortunately I don't have any water parameter testing equipment. Also, I heard from some people that aquarium salt is a miracle worker, but from others that it is a placebo. Isn't a betta a freshwater fish anyway? Thanks!
Aquarium salt and Marine salt are 2 different things. You would not want to add marine, table or cooking salt to the tank. Aquarium salt is for freshwater and for illness. It is an effective treatment against somethings, like Ich and some bacteria. It's much safer than antibiotics for the health of your tank as it won't kill your beneficial bacteria.
What you should not do is add it always. Some people do that but it is ill advised. It will become less effective for treatment and can cause harm in large doses or for too long use.
The amount I suggested for you it the low end of treatment dosing.
Other things can cause harm to the fish. Stay away from "fix".. like Melafix of Primafix, Bettafix. Those things can burn the betta's labyrinth lung.
To add to kthorkel's great advise, please be sure your Betta's water is warm. 80 to 82 is best. Do you have a heater?
Yes, my water is at a constant 80F. I also read somewhere that warmer temperatures encourage bacterial growth though? Should I lower it?
No, I think the warm water is good for Betta.s. I had bought a Betta from Petco that had some pretty bad fin rot, I kept his water clean and 82 degrees and he is now as good as new.
