Adding new fish with an established PBT

[hanas]

I have a Powder Blue Tang in my 150G reef tank with the following fish:

1 Yellow Longnose Butterfly
3 Resplendent Anthias
1 Mandarin

The PBT is barely 3" big and has been in the tank for about 2 months now. It has shown no aggression towards any of it's tankmates, but I'm contemplating adding 2 more fish. I'm a little hesistant due to their known aggression with new additions. Any thoughts on addiing these 2 fish:

Swissgurad Basslet
Lineatus Wrasse

My thought is to introduce them both at the same time.

I just added a moorish idol to a tank with a 3" pbt that had been there 2 months. The pbt chased and nipped at the body of the idol for a while, and so I turned out the tank and room lights and there was no problem the next morning.

It depends on your individual fish, but you likely will be fine if you get the new fish in soon and together given they aren't tangs or other similar fish. I would add them and any other fish you want in the tank sooner than later because the pbt may become more territorial over time.

I have a 5" PBT in my display tank with a bunch of angels for about 1.5 months. added a 4" blue tang(acclimation box for 3 days) and had absolutely no issues.

I seriously doubt a 3" PBT will care about an addition of a couple of wrasses.

pbt will likely not harass a wrasse and basslet. i've found that it will generally be aggressive towards new additions if they have similar body shape and size. wrasse/basslet look very different and the pbt probably won't care.

Both fish should be compatible with the PBT. PBT's are far less aggressive to species that are not surgeonfish and won't attack anything like a Sohal Tang often will. My main concern would be parasite introduction. As you likely know PBT's carry the track record of easily coming down with external parasites. I would be sure to quarantine whichever species you decide to get.
