6 blue/green chromis and two clowns?

I currently have 2 blue green chromis, 2 true ocillaris clowns, and some hermits and snails. Do you think I could add 4 more chromis to the group and a couple shrimp and still be safe in the tank I have listed below?

 

Yes but the chromis will likely fight for a while (possibly killing a few) to establish dominance

 

I know they have a pecking order but I heard if you have at least 6 no one gets to much abuse.

 

i cant comment on whether that is true or not... but i will say that the personality of each fish is different so its kinda hit or miss

 

Alright, know of any other schooling fish that would be a good fit?

Oh and second question what are some good herbavores to eat green grassy algae that arnt overly aggressive?

 

And i wasn't really looking at damsels cause of aggressiveness and wasn't to interested in tangs cause most get to large.

 

anthias but they are sometimes hard to get to eat in aquariums.
Fish that eat GHA... lawnmower blenny, you cant beat them lol

 

The name is already convincing haha I'll look into them, thanks

 

but keep in mind, they arent a cure for the underlying cause (GHA), only a fix for the results of the problem

 

It's not GHA only a little really short green colored mossy looking growth I wouldnt say it is out of control or anything
