Hey everyone, I was just wondering if there is any way to make my group of 10 Ember Tetras come out from hiding. I have added Corys to the tank, but they're still acting scared/shy. The tank also has Shrimp, some snails as well as the Tetras and Corys. I realize they may need more dither fish to come out, but the tank is only a 10 gallon. Please help. Thank you!
