when i looked in his tank today, i noticed an open wound in him. i’m not sure if it is a wound or if it’s a tumor of some sorts. i just moved him into a ten gallon tank 2 days ago from a 3.5 gallon. it has a sponge filter and a heater. the tank is also fully cycled. the tank is 80 degrees, it has aeration, and he has no tank mates. i feed him omega one pellets, and freezes dried bloodworms. i feed two to three pellets twice a day, and bloodworms every once in a while. i perform a 25% water change every week, and my water is coming from my sink. in his old tank i used to not use a siphon, but i’m going to start in this new tank. i use tetra aquasafe conditioner. i’m currently using test strips therefor the water parameters probably aren’t the most accurate.
ammonia: 0
nitrate: anywhere from 0-20
nitrite: 0
gh: it’s very hard. around 300 hundred.
kh: around 40
ph: 6.8
i first noticed these symptoms today. the only thing thats changed in his appearance is this wound. his behavior seems the same, he’s still eating, and i haven’t treated him. when he was in his old tank, he seemed to have some breathing problems. there were a couple days where all he would do was sit at the surface and breathe, he wouldn’t even eat, but over time he stopped. i assumed it was constipation. i’ve owned my betta since November 8th, and he was completely healthy when i purchased him.

Is there anything in the tank he could have gotten caught on or sliced by? Like under the filter or on a piece of decor? You might want to check by running something that snags easily (like hose) over everything. If it's more than just a minor snag on the hose it may be enough to cause such a wound.

Please fill out the form. I realize you probably answered many of the questions. However, this gives us what we need in a quick glance so we don't have to parse text. Thanks.

With it popping up that quick my best guess would be he's managed to snag himself on something in the tank. Do you have any sort of decorations, or driftwood in the tank?

As an example, I used some driftwood in one of my tanks for months and the betta in that tank never had a minutes problem with it. Since the wood was over large for the tank I eventually took it out and stored it. Months later I decided to use it in my larger tank, well the betta in that tank proceeded to try and squeeze into a hollow part of the wood, or try and get under the wood, no matter what I tried he figured out a way to hurt himself on it... Yep the wood is now out of the tank, and Hendrix the betta is finally not shredding his fins.

Adding some SeaChem StressGuard and Indian Almond leaves, or Roobios tea, will help him heal and prevent infection.
