125G STOCKING

[Tpepe321]

I have a 125G set up currently the only thing in here that will be staying is my Oscar. Final stocking idea is below, looking for advice on bio-load overload etc. I've looked into compatibility not interested in that as much so as bio-load input from planned stocking.
Red tiger oscar- I have a 7ish" red tiger Oscar in the 125g now (very mellow)
Electric blue acara- I have 4 currently growing out in another tank, around 2-3" early but looks like 1M:3F
Geophagus Tapajos- Plan to add 1M:3F (LFS has some that are large enough to sex)
Jack Dempsey - Plan to add 1
Green Terror- Plan to add 1
maybe some type of Vieja or Nicaraguan Cichlid if that wouldn't be over the top...

*****I understand there may be territorial issues, if there are I will relocate, not the issue here, interested in thoughts on bio-load / stock numbers / room for more/less*****
Lots of line sight breaks hiding spots heavily filtered weekly 30%+ water changes

What are your water parameters?
The oscar , Geos, and GT would prefer pH of 7 or below
The JD and nicaruguense would prefer pH of 7.5 and above

And with the top group of S Americans, or Central America group a 30% water change once per week any reach adult size, is a little wimpy.
I would do at least a 30% water change twice per week would, be mnimum.
If you combine all the above together, a 50% to 60% water change twice per week would be what I consider minimal

GT is from pacific side of the Andes and prefers neutral to alkaline water.

You said you aren't worried about aggression, this stock list that is the first problem. They may be ok until 3-4" then you WILL have issues. Mainly with the GT and JD.

I'd consider it crowded and overstocked for all of them as adults. It's not just a question of filtration, water volume, or even compatibility, but limited tank space and real estate-- in effect, the more large fish you add to a tank the more it shrinks from their perspective. You can mitigate space limitations up to a point by keeping social species or species with complementary behavior, feeding, breeding site, or water level preferences, but most of those fish will be direct competitors.

That said and ignoring the potential (or probable) compatibility issues you say you researched already, it might be temporarily feasible for young or juvenile fish.

Not suitable in the short, medium or long term. Too many fish that get large quickly, are territorial, and have different water type requirements. Not a good idea.
