Allen damsel

[norfolkgarden]

We recently received for Allen damsels from LiveAquaria.

They are pretty awesome and only an inch to an inch and a half long.
They are expected to reach 2 inches.
They are in a 75 gallon tank with the number of other fish that don't seem to mind them other than 1 of the dottybacks.
Should I add another 4 or more as soon as possible?
Not sure about the 'school of 6' theory or if they need even more to minimize aggression within themselves.
They are supposed to be less aggressive than most damsels but that's not a very high bar.

I had two together from that sort of size and they paired up and were fine with minimal bickering. I added another three small ones to up the numbers and they again were accepted. I now have two definite pairs but they still interact and are fine together. I'd say it's the more the merrier with these tbh.
