Capacity question...

[Agamemnon]

So, here is my 55 gallon fowlr tank (few softies), I've been set up almost 7 months now I think. A bit cloudy I know, just stirred up some sand before I took the picture. I really would like to get a royal gramma but I'm wondering if I have to room for another tankmate. As you can see I have alot of lr in there already. Heres what I have.

1- false percula
1- green chromis
1- barttlets anthias
1- blue spot puffer
1- purple firefish
1- pearly jawfish
1- randals shrimp goby

I change 10-15 gallons every 2 weeks, carbon and clearmax once a month. Nitrites are always good, most the fish are pretty small in size(except the puffer) so I suppose that helps with the bio load. Plus I only feed like every 3 days. Just thought I would post here for any thoughts or comments. If I can get him out I'd consider selling the randalls shrimp goby so I could get the gramma. As of right now everyone gets along in the tank, havent lost anyone yet since I cycled. Just don't want to push my luck. Thanks for any responses.

are royal grammas territorial or anything, if not you should be ok as they are all small fish

I think you can add at least a few more fish that are small med sized...
