Who Gives A Fish Forums

Try adding Indian almond leaves to the tank. They release tannins that calm bettas. I do 30% changes biweekly in my 3-gallon, and my fish barely notices.

I've been thinking about adding some new plants to my tank. Maybe some Cryptocoryne or Bucephalandra. Anyone have experience with those in low tech setups?

My 20 gallon has been running for 5 years with the same layout. I trim the Java Fern and Anubias regularly, but the driftwood and substrate haven't been touched. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. Maybe I'm just lazy.
