I recently got a trio from DD. They all looked ok the day of arrival, but one died the second/third day in, and he looked kind of rough. I imagine it must have been from shipping, b/c all of the other fish from that order (that are all in the same QT) look fine. I was really paranoid it was brook or something terrible like that, since the dead dartfish looked super rough with peeling skin. The other 2 are doing great, and are super cool. They are just chillin' like villians in the water column of the QT. I am really sad I don't have 3, b/c it would be so cool to see them always hanging out together in a 'school'. I think I will place another order for a trio from DD in a few months or so.
