Really want to add one to my 28 gallon to add a colorful lower-zone swimmer to the tank but the semi-aggressive description of the fish worries me. I only have a mated pair of Picasso clowns that host a BTA right up top right now, but I would like to add a goby and active swimmer like a firefish or small wrasse down the road and don't want a feud. Anyone house a neon pseuo and what are their observed behavior.
