Stocking input?

[Case]

Hey all.
I have a fluval edge 6 gal and I'm curious if i can add more fish. I currently have 4 Emerald Eye Rosbora's, 2 Bumble Bee Gobys, a TINY little horned nitrite snail and a small clown pleco. I want to add maybe a few more Rosbora's and possibly a Dwarf Blue Gourami.
I do an aprox 30% water change twice a week with a very light gravel vac with each to remove any gunk, an I have good filtration. My tank is well planted with live plants (and will hopefully grow nice and lush when i can get a hold of a small CO2 injection kit and better ferts)

According to aqadvisor.com you are already at 132% capacity so I wouldn't push it by adding any more.

I'd say your pretty fully stocked with what you got. I wouldn't add anything else

I'd say you're overstocked now and the fish are going to need a larger tank if you want to keep them long-term. Also depending on the type of goby you have they may need brackish water to live out their life-span.

Yeah I just realized that with the Goby after doing more research. The pleco's uprooted several of my water sprites and smaller plants to the point of tearing the roots and damaging them. I'm highly considering taking him back, along with the rosboras to set up a brackish tank with a few more Bumblebee gobys. How many goby's would be reasonable for my tank? I was thinking 4-5 in total with a few more snails.
