sure.
though certainly I've seen successful "cramped" tanks before...
again, this is assuming diligence with weekly maintenance and adding all fish of the appropriate size at the same time, but if you look at the first post I made, I had kept a 12 gallon aquapod for a year and it was even more "cramped".

Your aquascape will be key, as long as each female has AT LEAST one separate place to call home (like an overhanging rock, a cave or some good macro growth) you will really enjoy watching the larger male "tend" to them both. doubt you would see any significant aggression unless one of them actually spawned, and even then, once a harem is formed, they tend to tolerate one another very readily and have even been reported to share in the husbandry new fry.
"cramped" yes, impossible?
no.

I agree :biggrin: and well put. These fish are quite small (max 4") so 2 or 3 in a 14 gallon (I'd assume 24x12 floor space) would probably be just fine. I was just worried about them not getting along and am probably thinking they are more aggressive than they actually are.

Hmmm 3 Royal Grammas you say... hmmm :D
AA is getting in a load of fish on wednesday night so I'm going to check out what they have on thursday. I'm sure I'll be coming home with something...
speaking of which, add a green ric and purple/green mushroom to my list
