Re: Reef Safe fish?
I usually avoid these types of threads.
"Reef safe fish" = poor choice of words. If a fish occurs in, on or around a reef it eats something in, on or around it.
So we use the term "reef compatible". Research compatiblity and you'll be much more successful.
upfront disclaimer: I'm a poor example to follow when it comes to fish stocking. I do know a few things about stocking fish in a reef aquarium. It's very important to remember that although you can read about generalizations regarding a fish species
every fish specimen may have a different idea what tastes good.
IME Pyramid Butterflies (and other planktivores in general) are much more of a challenge to keep than other types of fishes.
If you want to keep planktivores you'd better have a really good filtration system. Anthias and other Planktivores are better suited to LPS/softy type reef aquariums than SPS (clean) type displays.
IME Copperband Butterflies are easier to keep than Pyramids. (This isn't an opinion you'll often hear.)
None of these Butterflies are good species for the beginner although it's usually cited that Pyramids are "easy".
I wouldn't try a CBB until the aquarium develops a strong population of microfauna. Give the aquarium at least one year.
The only Rabbitfish I trust in a reef aquarium are the Foxfaces.
Bicolor and Magnificent are the cream of the crop but the more common types are great choices for aquariums IMO.
I recommend avoiding Blue Lines, Scribbled, and Orange or Goldspot Rabbitfish as they are potential reef wreckers IME.
If you know what species of Tangs you're going to add that's great. I would introduce them from least aggressive to most aggressive- not all at once.
Obviously you need to pay special attention when adding Acanthuriids because they're prone to carrying disease.
I only add Tangs to my aquarium that I know are "clean".
Ctenochaetus Tangs are underrated by the vast majority of aquarists.
Wrasses would be my most important suggestion IMO.
Get some Flasher and/or Fairy Wrasses. Get a yellow coris for pest control. Cover the aquarium!
I was asked to comment on Angelfish.
There's no brief summary that can be made of them except that if you want an Angelfish in your reef aquarium be prepared to make some sacrifices. 180 gallons is probably the smallest size aquarium you should place an Emperor. Personally, I'd go with a smaller species in a 180 although all the Centropyge species that I've ever kept have been worse coral nippers than their larger cousins.
For a 180 reef I'd be leaning towards a Majestic, Flagfin or a Regal. JM humble O
