I have a 210 with a sailfin who is 3" long and one inch wide. A pig. A healthy yellow too. Recently had a PBlue T, same size, got through the mail in the winter, arrived cold, aggressive slow drip, eating after a few days, no QT; ate for a few weeks, then progressively got worse and worse ich, pulled him out to a QT; died shortly thereafter.
Grabbed a Pbrown T from a LFS, 4", QT for 10 days, no hypo; looked just fine, eating real well. Added him to the 210 since I am going on vacation and the hypo won't work well with a neo watching the system.
The YT and SFT are being bastards. Worse than with the blue T. I can't pull apart the reef; will have to wait and see and will add my luck to this thread.
