Greetings all :)

I currently have a standard 29 gallon with a 20 gallon sump beneath. Bubble Magus Curve 5 skimmer. 5 gallon weekly water change. Nitrates never jump above 3.

Current stock:
Wyoming White Clownfish, male
Blue Devil Damsel, female
Sailfin/Lawnmower Blenny, gender unknown
Blue/Purple-side Fairy Wrasse, female
Adding a Male Royal Gramma this week.

I have had no problems with aggression thus far. The Wrasse and Damsel occasionally toy with eachother, but other than that these fish have been model citizens. That being said, as long as I have no problem with the new Gramma, could I safely add a sixth fish if it were a bottom dweller (such as a goby) or a percher (such as a hawkfish)? Thank you all so much for your time and advice, and happy reefing! :)

Fish usually don't get feisty/aggressive until later. I kept 4 in my 20g long. My adult clowns were mean, my blenny turned mean and my gramma was crabby. They were all fine for the first year though. :p I can't imagine the fairy should be in a standard 29g for long though.
