I am new to the hobby and established a 6' 175g primarily new world cichlid tank four months ago and have been slowly adding mostly juvenile fish. Everyone is getting along fine to this point and all are healthy. I am concerned though that I may have been a bit too aggressive in stocking and as the fish reach maturity I may be overstocked. Also, I am currently running a Fluval FX6 but think I will need more filtration so am thinking of adding a second one.

I am very interested in opinions. Here is the stocking list:

Severum - 3
Koi Angelfish - 1
EBA's - 2
GEO Tapajos - 2
Columbian Tetras - 6
EBJD - 1
Polar Parrot - 1
Bristlenose Pleco - 1

First problem is the EBJD are very disease problem and don’t live much longer than 2 years so I wouldn’t do them. I personally don’t like the polar parrots so I wouldn’t include them but I can’t gibe you any advice on them. I would personally take out the 2 I mentioned and add more Geophagus as they like to be in groups. (4-6)

Welcome aboard
Once those fish mature it may be overstocked imo.
 
The 1st question I always anally ask, is what are your water parameters? (pH, hardness, conductivity)

The reason is cichlids, like many EBJDs and the natural ancestors of the man induced parrots , came from hard water, higher pH species.

The others on your list, are soft water, neutral to lower pH species, and most of them are legitmate natural cichlid species.

In most cases the man made types will reaily adapt to average water conditions, but you never know.
But sometimes, natural species have evolved to live in specific water parameters, and are able to resist the only bacteria that hail frome those conditions.
This is why, we often see cichlid like severums, afflicted with HITH disease as they age, if subjected to hard water conditions

It may depend on the water conditions they were bred in
