about to finish stocking tank just a couple of questions

[willie]

Hi guys, I am about to add the last few fish additions to my reef. Just a quick once over.
I have a 90 g tank, 30 g sump/refug and I have about 250 lbs of lr.
Current residents are:
3 inch yellow tang
2 1.5 inch false percs
1 scooter blenny
1 lawnmower blenny
About to join after their quarantine is up:
2 green chromis
1 1 inch long 6 line wrasse.
What I want to pick up this week to finish off the population:
yellow eye kole tang
engineer goby
flame angel
Does anyone see any issue with this group? My main concern is the 2 tangs but I have read posts that say that the 2 being different shapes will likely leave each other alone. What do you guys think?
here is a couple of pics because its been a while since I posted any.

Hi,
Go for the flame angel, he will add some pretty to the tank. The engineer goby is a monster digger, and the Kole tang is a dull colored nothing kind of fish. I had a Hippo and Kole at the same time in my 90g...the Kole was part of the CUC.

All the fish look okay, but I'd skip the engineer. They destroy sand beds and if your rocks aren't sturdy, get prepared for them to come down. They get really, really large as well.
