hmm.. questions about fish...

[linz13]

hey guys! i'm new to aquarium advice! just wanted to aska few questions...

i have just recenntly decided to start a 55 gallon reef tank.. i had a 13 gallon before for about 3 years and decided to upgrade so now here i am...

ive had my 55 gall. tank up and running for about 3 months now... and i just recently got some new corals... green tree leather coral, frogspawn, green star polyp, and zoanthids... theyre just frags right now but hopefully soon theyll all begin growing!

for fish, i have a byno goby (sand sifter), a purple pseudochromis, and 2 percula clowns... i was wondering if i could get a flame angel and a yellow longnose butterfly fish... i wouldnt be getting them for a while.. and these would be the last two additions to the tank... i wanna do a lot more research on them but just wanted to know what some of your thoughts were... are these fish generally reef safe? i've been told that the flame and the bfly were pretty much reef safe... but i want to get some other opinions too!

i have about 40 pounds of live rock and 60 pounds of live sand in there too... tank is fully cycled and coralline algae is growing.. cleanup crew consists of one cleaner shrimp, one sally lightfoot crab, 20 assorted snails, and 5 hermits...

any advice would be awesome! and thanks in advanced!
