What To Add First - Figure-8S Or Bumblebee Gobies

My 29 gallon BioCube is ready for the Figure-8S & Bumblebee Gobies, but I was wondering what I should add first & if it mattered. The plan is to have 2 figure-8 puffers & 5+ or so bumblebee gobies. I was thinking of putting the gobies in 1st in order to let them setup shop & then get the puffers after the gobies had familiarized themselves. But I was wondering since the gobies are so territorial will the puffers be able to make themselves at home. Also are the numbers of fish I'm adding ok? I dont want to overload & I dont want the puffers fighting, I've been told to either get get 6+ puffers or get 1. Any thoughts would be greatly appreciated.

Here is the tank & how it looks now:

That should be enough room for 2 Figure 8's & 5 BBG's. They say 15USG for your 1st Figure 8 and 10USG for very extra one after that.

I've had 2 Figure 8's living with 4 BBG's for about 2 years without problems and they were all introduced at the same time however I have read that some people's puffers have ate their BBG's and for this reason I would say to introduce the gobies first.

Agreed - let your bbg's establish themselves in the tank first before adding the F8s My swarm of 9 bbg's were established in my metre long tank prior to adding my 2 F8s

Tank looks great btw!
