Advice on stocking Fluval Osaka 260L

Hey, brand new to 3reef. I have a fluval osaka 260l. I have 70 lbs of live rock with a 3" live sand bed. Need some stocking ideas I am new to saltwater. I plan on doing a reef tank, but my light needs to be upgraded.

I currently have:
2 True Perculas
4 Turbo Snails
4 Cerith Snails
10 Assorted Hermit Crabs

Wanting:
1 Kole Yellow Eye Tang
1 Shrimp/Prawn Goby
1 Lawnmower Blenny
1 Royal Gramma

Would this be fine? Would I be able to put anything else in? If so, what else would be good? What order should I get them in? I have been told that I should put most aggressive last.

Help would be greatly appreciated.

 

Welcome to 3reef Ryan.

Order of addition: Next I would do the Goby and Shrimp combo, next the Royal Grammma, the Blenny and last the Tang. All the fish listed are on the smaller end of the scale with exception of the Tang.

That leaves you at six, because most of the fish are of the smaller variety, you might consider a Wrasse or Dwarf Angel.

 

What about dartfish?

 

IIRC the Fluval Osaka 216 is 70 gallons but only 40 inches long, which is too short for a tang. :-/

 

Sure a Dart fish, just remember they are very shy and might be intimidated by more aggressive fish like clowns.
