It all depends on the fishes personality. For some, some have worked and for others some haven't. Seems like you have plenty of tanks to be able to safely go through trial and error with sucsses. I would be careful with the retic while its small though.
Edit: As far as combos that dont usually work Ive kept a huge FH and GT with my rays with sucsses.
