Next week I will be purchasing an EBJD from my LFS. It will be going into a 55gal tank with a divider, the only things on his side of the divider will be 4 cory cats for clean-up and on the other side is a Female JD and a severum. I was wondering if I could keep 3 black skirt tetras as dithers for the EBJD to make sure he isn't hiding and stressed out all the time. The EBJD will be about 1''.
