Haven't gotten that far yet. Thinking a couple clowns and a Yellow Tang are first on the list. I really want a Blue but have heard that Hippo Tangs can be aggressive so I am not 100% sure about that.
We have a cardinal, yellow tail damsel, and a flame angel on the list as well.
Suggestions:
Most Damsels are tough and territorial. If you're going have one in your tank, it's generally a good idea to add them last. Oddly enough, Dwarf angels, (Centropyge....like the Flame) are also territorial, as are Tangs, although the Yellow is less territorial than others.
Clowns are fine and do not need an anemone for health and well being. Anemone's are beautiful and also among the most difficult and frustrating critters to keep in the aquarium. Dont even consider putting an anemone in your tank until it's been running for at least 6 months.
Your tank, (and you) will go through ups and downs and various fluctuations until things settle down. 6 months is generally regarded as the minimum time to introduce an anemone to a new tank. If you're going to be keeping an anemone, you will want to do your research and determine what type and what conditions it requires to be happiest. If it's not happy, it will move. Sometimes this results in an anemone wandering into a powerhead or pump intake which results in a severely damaged anemone (if you're lucky) or a dead anemone and in some cases, dead fish, (I've experienced both...it sucks to put it bluntly).
Skipping an anemone makes things easier for you and as I said, the clowns dont need one.
Personally, I would add the Cardinal(s) first as they are the most docile fish in the group. Get them acclimated to your tank, eating happily and regularly, and then I would introduce the clowns.
After the clowns, I would add whatever other filler fish you guys like, (wrasse, basslets like Royal Gramma's etc, fire fish, rabbit fish etc), then I would add the Yellow Tang, then add a larger Flame Angel, (as in larger than the Tang) and then finally, if you still wanted it, I would add the Damsel.
Last suggestion...QT your fish.
Putting fish in QT before you put them in your display does two things...
Keeps new and exciting diseases from your tank, (Velvet is definitely exciting...it can wipe out an established tank in 48-72 hours!), and it allows you to get a new fish that may be shy or a picky eater acclimated to captivity and you can get it eating prepared foods better.
QT for a 90 gallon doesnt have to be big or expensive...just a 20H on a homemade stand, (or the floor) with a HOB filter and some PVC fittings for the fish to hide in. When its not being used, just empty it out, dry it off, and put it away. Keeping a couple of bioballs in your sump is a good way to make sure you can instantly start up your QT. I usually keep 3-4 in my sump floating around and if I start up the QT, I just fish them out, and put them in the HOB filter. The HOB filter is more for water movement and aeration than anything else. I dont use floss or filter media in it...just put the bioballs in and let it rip.
Just some thoughts, and good luck with your tank, I'm sure your kids will love it.
