Green chromis

Are Green Chromies less aggressive than Damsels? And if I were to get some for a 180g reef, do you think 3 or 5 would be ideal?

They are less aggressive than damsels. They would be appropriate for your 180; either 3 or 5 would be fine...depending on what else you're planning on adding to your tank.

If they're blue-green chromis (same-same I presume), indeed they're very amiable fish.
Our first fish were a pack of 5, and they're quite entertaining. Schooling around, and they very quickly figured out the feeding procedure. We then added two clowns, and they all got along nicely, even mingling from time to time.
I do understand that it's better to get several, and in odd numbers.

They are damsels. Typically, however, there aggression is turned inwards towards each other and not other fish. The more you get the more the aggression will be spread out and no single one will be picked at. I've also found that by feeding small amounts, throughout hte day every day, the aggression is limited.
They do school (at least the small ones. Some people have reported that as they mature they quit schooling). Mine have never shown any agression to my two Occ. Clowns or my Anthias. They all swim around together.

I have 5 chromis and 2 clowns in a 90 gal. They get along perfectly.... swim together high and low.. sleep in the same area. Not the case with my boring/not fun/independent/attitude prone/yellow tail blue damsel who doens't socialize at all, hides all the time low in the tank... and feeds on the leftover of his tankmates.

I've got 3 in my 75 and they are great. They school together and are very active, surfing the current in the upper part of the water column. They are usually up near the top, within the first 6 inches of the water. They are in the tank with a firefish, a lawnmower blenny, a coral banded shrimp and a bunch of snails and hermits. They dont bother a thing although I think if the coral banded could catch one there may be trouble.

I have 5 in my 150. They only seem aggressive to each other and even that is pretty limited. They are gorgeous as they change color depending on how they light hits them - sometimes green, light blue, neon blue and occasionally silver/grey. Very active and are always swimming around. And as f14peter said, they quickly learned the feeding schedule. They even get excited when I put algae sheets in for the tangs.

Mine appear to glow in the dark when found with a blue/black light flashlight. Initially, I was shocked and concerned, but understand that to be normal.
