what else for the list?

I have probably changed my fish list about a million times. I'd like to get it narrowed down some time soon.

I have a 90g currently with:

2 ocellaris
1 striped bristletooth tang
1 solar fairy wrasse (added yesterday to the tank)

I would like to add:

1 long nose butterfly
1 yellow watchman goby
1 diamond goby

Would I be able to add some anthias of some sort (perferably lyretail)? If that would be to much for my tank, would i be able to add another wrasse? If so, what type do you recommend would get along with the solar which I already have? Thanks for the help.

 

Anthias require a lot of feeding so if you can't feed them 3x a day, I would skip them altogether. Other than that, your list looks fine, assuming you don't have any corals as the butterfly could take a liking to them.

 

I am planning on making it a reef. After doing some research, I am under the impresion that the big longnose butterfly is reef safe and the yellow longnose is the reef safe with caution. I will be able to feed the anthias 3 times a day, so that shouldn't be a problem. How many lyretail anthias could I have? or is there another type that you would recommend?

 

You can have as many anthias as your tank can handle and the kind that you get is entirely up to you. I like the looks of all of them so I'd have a hard time chosing

No butterfly fish is 100% reef safe so if you're prepared to pull either butterfly out of the tank if/when it starts eating corals, go for it. They're beautiful fish

 

If your planning on making it a reef tank then count on keeping 0nly 3-5 fish max. And since you already have a fairly large fish in your tang, I would keep the others small. If you plan on keeping any shrimp then I would be cautious with any wrasses and hawkfish. Also forget about any butterfly and angel fish as they are generally not reef safe.
Some nice reef safe fish are Canary and Midas blennies, Royal Gramma, Six line wrasse, any of the fire fish, flame, coral and longnose hawkfish to name a few. Beware the wrasses, hawkfish and fire fish are jumpers, so you will need a top for the tank.
If you dont have one yet, you should buy a good book on marine fish such as
A PocketExpert Guide- Marine Fishes, there is also one for reef safe fish too.
