No more tank deaths so far!

Been a month since my last fish death. Tank's a 20 gallon with 6 Neon Tetras, 4 Corydoras, and a Betta. Parameters are stable, 0 ammonia, 0 nitrite, 10 nitrate. Using a sponge filter and weekly 25% water changes. Anyone else had a streak like this?

That's solid progress, man. Stability's key with Bettas, especially in community setups. What's your temp at? I've found keeping it at 78°F with a reliable heater cuts down on stress. Also, what're you feeding the Corys? They can be picky if the substrate's not right.

My tank's been stable too, but I've only got Guppies. They're hardy, so not sure if it counts. Do you think the sponge filter made the difference? I've been using a hang-on-back but might switch.

Nice work! Sponge filters are underrated for biofiltration. How often do you clean it? I've got a similar setup but with a canister, and it's been smooth sailing for 3 months now.
