Thanks for the welcome. I was surprised to find this forum focused on these little fish.
I will add more plants to the tank, but I want to try something more. I can either slightly increase their school, or add a small school of something else in the tank. What would you do in my place if you had this problem?
I almost never see them. They didn’t seem so timid in the store. I researched their natural environment and requirements before buying them, but I forgot to look up their behavior. I figured Danio = bold and active, but I guess not. I put a school of timid fish in with a timid fish *big sigh*.
