Hello Ryan, I just started my tank this year and also want a "aggressive tank"
. At this moment I have a snowflake eel (small), and a Radiata Lionfish. I plan on getting a Huma trigger, and probally a yellow tang. I was told from the different LFS
that my 55 gallon would be good... although I got a Radiata lion instead of the Volitain because the Volitian would surely outgrow my 55g. I was also told to get the trigger last.
From what I know they have to be with fish that are big enoegh not to be swallowed! I really would like to get some clowns, but I am concerned about there safety, so I won't.
Hope this helps alittle!
