Okay...so it is a 120, but 5'? I read so many posts and I think this one had me confused because at one point something was mentioned about a 75g..
. Will the yellow be okay in a 5' tank? Probably yes, but ideally I still feel that Tangs outside the bristle toothed group do better with 6'. Tank size does not directly kill fish, but it can cause stress, which often leads to health issues, which often lead to shorter lifespans. I try to go with larger than "minimum". That's just me.
I think the rest of the list looks good though. The squirrel fish was just an FYI as some people purchase fish like that not knowing they are nocturnal and then are disappointed when they don't see them much. They are great looking fish...just saw three at my LFS
and was considering possibly getting a couple for my 240g.
Keep an eye on the new Tang. I've always heard that you should add Tangs at the same time or there can be aggression issues. Never personally experienced that though.
