Crowntail Betta With Curled Fins

I got a beautiful crowntail 7 months ago, his tail has grown tremendously sense I got him, awhile back I noticed the ends of his tail started curling. I thought it was due to his tail growing to rapidly but today I noticed a piece of his tail on the bottom of the tank. I shined a light on him and I also noticed spots on him. Doing some research I found out it could be fin rot, I've never dealt with fin rot and wanted opinions. Besides the fin on the bottom of the tank hes seems healthy, he has a bubble nest, eats, and is active. He has always had dark tips to his fins and some black running through his fins so its hard for me to tell if hes sick or not. I'm posting pictures from the day I bought him (top) about 3 months back, and today his spots and the missing chunk (bottom) Please any help is appreciated and if its not fin rot what can cause the curling tail?

 

He has fin rot as per the last picture.

The curling is new growth, either obstructed by fin rot or just poor shape. It's mostly normal in his situation, it might improve.
What you should probably focus on is curing that fin rot. The healing will take care of itself once his fins aren't rotting.

 

HI there. I agree it looks like fin rot. For treatment you have two options. First option is to do every other day 50% water changes along with adding Aquarium salt. Continuing for 7-10 days.

The second option is using an antibiotic. Nitrofurazone is the antibiotic you would need. It is found in Jungle Fungus Clear tabs, Tetra Lifeguard, or API Furan-2. You will need meds in the tank for 7-10 days. This is usually 2 full rounds of meds.

Your guy's case is tricky. Crown tail fins are hard to determine how bad it is, until it is severe. So it is really up to you whether or not to Medicate. You could do the water changes and AQ salt for 4-5 days, see if it helps. if it doesn't, then switch treatment to the antibiotics if you want too.

Thank you so much I’ll start water changes and salt to see if that helps and if not I’ll medicate

Thank you I’m going to try and core the fin rot right away. His water temp was also sitting at about 71 for awhile. Today I went and got a new heater and it’s coming up. I was concerned about fin clamp but wasn’t sure about that either

 

You definitely need to get that temp up. 71 is almost 10 degrees too cold. So if you can cover the tank to hold some heat in, I would do that.

With the AQ salt the dose is 1 tsp for every gallon. You will take a cup of tank water and dissolve the salt in the water. Then add the salted water back into the tank slowly over a couple of hours. You may need to add more water to the cup to be able to dissolve all of the salt.

Now with your water changes, you will be removing the salt with the changes. So if you remove 2 gallons of water, you will add 2 tsp of AQ salt into the replacement water, before filling the tank. On the last day of treatment, with the water change I would do a 75% water change. Don't add the salt back in, and the salt will be virtually non-existent in the tank. And will be removed fully with one more water change, even if it is a week later, during normal tank maintenance.

Thank you so much I have started treatment and the temp is already up to 76 and he is already more active
