Choosing new fish (Temperment and tankmates)

[Kingster]

So I already have a tank right now.. 120 5 foot tank with neon tetras, flame back bleeding hearts, apistogramma agassizii, blue eye pleco, and 4 Myleus sp green

i may be up grading the SDs to a 200 gallon tub whitin the next year

Iam only considering adding 1 of the following species, 2 at best... 2 of these I would have already croased off for aggression bit I wanted to hear what experiance other people had with them first

I am considering adding one or two of the following:

Hoplarchus

psittacus

Pterophyllum

Altum

Heros

severus

Crenicichla

coppenamensis

Andinocara

stalsbergii

Myloplus

torquatus

If you're keeping the current stock minus the Silver Dollars I wouldn't add any of those fish. All of the those fish will eat the neons, there's a good chance the bleeding hearts would be killed or eaten by the pike or Andinocara (at the least they wouldn't be happy) and the same would apply to the Apistogramma. I also wouldnt trust full grown Silver Dollars with the neons. Thats my opinion. Hope it helps.

I agree with the above, if you want to keep the neons, maybe even the bleeding Hearts, every one of the fish on your list will, if opportunity presents, eat them.
And in the case of the Apistogramma, some (not all) on the list may present territorial issues, and size alone will put the Apistos at a distinct disadvantage.
All except the Andinoacara are soft water species from east of the Andes, the Andinoacara from west and in my anal way of thinking doesn't fit in geographically with the rest, but beyond my querky reasoning, th Andinoacara would be the one most likely to polish off any tetra smaller than something similar in size to it, and being very territorial one most likely to to kill any other cichlid it deemed a turf usurper.
In my current tank (similar in size to yours (a 180)) I cycled it with about 2 dozen 1 to 2" mosquito fish. Once I added young Andinoacara (coerleopunctatus, this species maxes out about 1/2 the adult size of stalsbergi) the mosquito fish lasted no more than 2 weeks .
I do have a couple tetras with the Andinoacara but they are comparable in size.

Bleeding hearts get pretty big. If yours are mature, they might do okay. Everything eats neons, even angelfish.

Yuh I just wanted to hear what other people have experianced.. My myleus sp green currently are a good 5 inchs and could swallow a cardinal yet they usually prefer to bed for food and bite my fingers instead for the time being.. I was thinking maybe go with afew altums and 1 severus

Buying the angels and the severum as juveniles will at least buy you time with the neons. I have kept many different types of tetras with Severums with no problem in a 180 but nothing as small as a neon. I had about 30 Oto cats in there and then suddenly there was 25, then 20 and I couldn't figure out what happened until I turned my lights on in the middle of the night and my Gold Severum had one in his mouth. He was just picking them off the glass at dusk like a treat haha. So I have no doubt a full grown Severum will eat the Neons as well.
