Who Gives A Fish Forums

Thanks for the advice, everyone. I'll test the water today and check the heater. It's a 10-gallon tank with a sponge filter, so the flow's pretty gentle. No tankmates, just him.

I've had my betta for about six months now, and I'm not sure if he's doing okay. His fins look a bit ragged, and he's not as active as usual. What are the best ways to check if he's healthy?

I switched to sand last year, and my water's been way more stable. Plus, it's easier to clean. Just siphon the surface during water changes.

I use a liquid test kit for ammonia, nitrite, and nitrate. It's more accurate than strips. Also, adding live plants like anubias can help absorb some of the waste.
