Heard Emperors are difficult to keep, any truth in that?
alot of truth to that, I have never been able to keep one long term. They are fairly sensitive fish, but once established they do well.
The clown trigger is not a good idea, as stated above they become very aggressive as they grow. Having a lion limits your possible tankmates, including most triggers and puffers. I keep a blue jaw trigger with my lions, and although many people steer clear of triggers all together I have never had an issue with blue jaws.
Tangs make good tank mates for lions, but I would hold off on them till you set up the 180, a tusk is also and excellent choice. For now you lion will be pushing the bioload in a 100 when it is fully grown, which will be less than a year from where you are now.
