Will these be ok in my tank?

[Doglips56]

I recently purchased a pair of pajama cardinalfish. They have been in QT for about a week now. They seem active and healthy but aren’t voracious eaters. My style of QT (though I know this is a controversial subject) is to observe before I medicate. If they aren’t visibly ill or in distress I like to watch their eating elimination and general behavior before I add medications.
Anyway I digress...I was doing some more reading on them and it said they should be placed with similarly peaceful tankmates and I wanted to know if those of you with more experience could tell me how to eventually introduce them into my 125g DT.
I currently have one 3-4” hippo tang, 1 small royal gramma, 2 small clowns and a small chromis. The small fish are no more than an inch or so each.
I wouldn’t consider them to be particularly aggressive but I do kinda feel like the hippo rules the roost, especially at feeding time. There is also 1 fire shrimp and some snails and hermits. I have a lot of rock work with a couple of large arches and several available caves/holes.

I also have on my wanted fish list:
lyretail anthias...would like several if I can get the correct ratio of male:female
Lawnmower and/or starry blenny
Fairy wrasse or yellow coris wrasse
Possibly another smaller tang

I don't think you have to do anything special when putting them in. As long as they get some food it should be fine. You may have to spread out the food in the tank if their tank mates get food before they can manage to grab a bite but again I think its fine.
