Betta fish and disease prevention strategies

Post by fruitymint »

What's the best way to keep my betta from getting sick? I've got a 5-gallon tank with a sponge filter, heater set to 78, and do weekly water changes. Still worried about fin rot or ich.

Consistency is key. Test your water weekly for ammonia, nitrite, and nitrate. Keep nitrates under 20 ppm. A stable environment reduces stress, which is a major factor in disease. Also, quarantine new plants or tankmates for at least two weeks.

Yep, stress is a biggie. I'd add that overfeeding can mess with water quality. Stick to small portions they can finish in 2 minutes, twice a day.

I've had good luck with adding Indian almond leaves. They release tannins that mimic their natural habitat and have antibacterial properties. Just toss one in and replace it every few weeks.

My guy got fin rot last year. Fixed it with daily 10% water changes and a bit of aquarium salt. Took about two weeks to see improvement. Now I'm extra careful with water params.

How often do y'all clean the substrate? I've got sand and worry about gunk building up. Don't wanna stress my fish with too much messing around in there.

I vacuum my sand lightly every other water change. Just skim the surface to avoid disturbing the beneficial bacteria too much.

If you're using tap water, always condition it before adding. Chlorine and chloramines can wreck their slime coat, making them more prone to infections. Seachem Prime is my go-to.

Also, watch for signs of stress like clamped fins or hiding. Catching issues early makes treatment way easier. A happy betta is a healthy betta.
