Stephan1973 Posted March 16 Share Posted March 16 I am new to Black Phantom Tetras. I thought I enjoyed the Red Phantoms but wow these Black Phantoms are amazing. I currently have 3 in a 20G with 3 juvenile bronze corys, a Koi Betta, one large mystery snail and a dwarf Mexican crayfish. They all seem to be very happy and no chasing or fighting. But I see the Tetras change their colours from a dark almost black to a silvery colour. Is this normal? I included some internet pics to give an idea on colour Link to comment Share on other sites More sharing options...
Katherine Posted March 16 Share Posted March 16 Mine do this too. I'm not sure about why. Link to comment Share on other sites More sharing options...
Birdsnstuff Posted March 16 Share Posted March 16 I have some and I’ve decided the males change colors when they display to each other and females. All the posturing is fun to watch. Link to comment Share on other sites More sharing options...
Stephan1973 Posted March 16 Author Share Posted March 16 I have Red Phantoms and loved them but these Black Phantoms are amazing. Debating on getting more. wondering now if the colour changes are posturing. Thanks for thought on that Link to comment Share on other sites More sharing options...
