Betta Fish: Fin rot?


I think my boy is experiencing some fin rot. What do y’all think? What’s some good advice if so?

    • Tank size: 5 gallons

    • Heater and filter? (yes/no): YES

    • Tank temperature: 78-82 degrees F

    • Parameters in numbers and how you got them. Key water parameters include the amount of ammonia, nitrites, nitrates, and pH.:

    (test strips) nitrate: 20ppm // nitrite: .5ppm- 1.0ppm // GH: 75 // Chlorine: 0ppm // KH: 40ppm // PH: 6.8-7.2 // Ammonia: 0-0.5

    (I DID A WATER CHANGE 10/31/2025)

    • How long have you had the tank? How long have you had your fish?:

    Had both tank & fish a little over a month

    • How often are water changes? How much do you take out per change? What is your process?:

    I take out 25-30% of the water & exchange it w/ conditioned tap water weekly (every 7 days).

    • Any tankmates? If so, please list with how many of each:

    He had 5 shrimp for about a week & killed them all 😭🤷🏽‍♂️

    • What do you feed and how much:

    Feeding “Hikari – Betta BioGold pellets” & occasionally freeze dried blood worms (rehydrated)

    • Decorations and plants in the tank:

    I don’t have a biosubstrate but it’s a heavily naturally planted tank (that I really just added to & finished, lol don’t judge getting fertilizer tomorrow) all of my plants take from the water column.
