How many more fish can I add?

[stems]

Hi guys,

I have a 90 gallon DT and a 20 gallon sump. Currently, the DT has 1 lineatus, 1 sunburst anthias, 1 lubbock's wrasse, 1 lawnmower blenny, 1 clownfish, 1 firefish, 1 purple firefish, and 2 pintail wrasses. I was wondering if I could add anymore fish in the future, such as a borbonious anthias?

I haven noticed some aggression from the lubbock chasing around the pintails to a corner once every 1/2 hour or so, which may be because I just put in the pintails a couple days ago. However, I am a bit worried that the tank may be already overstocked as well.

You could probably add another fish like a borbonius. The cirrhilabrus wrasses you have are generally prettty peaceful as are the others. I'm guessing your lineatus is your biggest fish so your tank doesn't seem too crowded.

yeah, the lineatus is the biggest at about 4 inches whereas the other fish are about 2 inches. And ok cool, thanks for your suggestion.
