What Else Should I Add?

[Mattmez]

I have a 125 gallon that I haven't really stocked yet. I just moved my fish from my 55 quarantine in to it. It currently has 1 angel, 1 BGK, 6 diamond tetras, and 6 cory cats. Would else should I add I want to stay South American (amazonian) I will post below what I am planning to do. But I was wanting some suggestions.
Stock list for 125 gallon

4 Angels

1 Macana Zebra knife

1 Black Ghost knife

8 assorted cory cats

4 black neons

10 diamond tetras

4 geophagus Jurupari

4 tiger silver dollars
By the way the black neons are food that the angel never ate

Hi and welcome to the forum. I can see one or two problems with that list. Firstly the angels - when buying angelfish it's always best to buy them all together as young fish and allow them to grow up together. Once you have an angelfish added further angelfish can be incredibly difficult to nigh on impossible. The problem is that angels are highly territorial and so now your lone angel will see the whole tank as his or her territory and any further angels added are subject to attack. I've watched an angel attack another angel added to it's territory and it was prepared to kill. 
 
The next thing would be your tetra's. Tetra's are shoaling fish and so need to be kept in large numbers - 10 or more of each species being the recommended and adding them with an angel could be difficult (I've just seen your comment about neons being angel food and so if your angel has already eaten some tetra's it is more than likely going to do it again)
 
On to the cories now. Again a shoaling species that need to be kept in groups of 5-6 or more but they need to be in groups of the same species so for example 5 to 6 peppered cories, 5 to 6 panda cories and so on. 
 
As for the rest of your list - none of those are fish that I've kept personally and so I can't comment on those but I'm sure someone else will be along to advise on those

Hi thanks for the reply @akasha72 by the way I saw the black water setup you have and it is very nice. It is very similar to what I had in my 55. I am planning to do something very similar in the 125 gal. The diamond tetras are big like 4 inches and are impossible for the angel to eat. They also have a big "girth" that the angel can't get its mouth around. With the cories I have 5 wild caught corydoras spp. And 3 more unidentifiable cories. The problem with the angel is that when I bought him was I had the 55 gal. I didn't want to overstock it with another... So I am in a bit of a pickle now but I think I can make it work

Any other suggestions??

Black Ghost knife grows into a big fish, I had one I was looking after for a few weeks, Cool fish but it ate most of my Shrimp and he was only about the same size as my Pearl Gourami. Dont miss it.

I am just guessing here, If your angel sees it as food it will find a way of eating it. All it needs to do is take a chunk out of it first and the rest as they say is angel food.

I keep my angel pair with emperors, black neons (only a few left now and I'm not replacing them) and harlequins but my pair have never attempted to eat any of my smaller fish. It would seem some angels do and some don't. My pair grew up with the harlequins and black neons and there are other stories out there of angels that grow up from babies with small fish seeing them as 'family' and not 'food'. Sometimes it works, sometimes it doesn't. So long as we are aware (which you clearly are) then I see no problem with trying.
 
Thank you for your kind words regarding my tank

I completely concur with what Akasha wrote in post #2.  [Also agree with latest, but in #2 she nailed it.]  Nick too for that matter.
 
Moving beyond these...do not mix knife fish.  The BGK will be better alone at this point.  The fish will need a tank no less than six feet in length and two feet in width (front to back) so it can grow and maneuver properly at full size which should be close to 20 inches, and has it is inflexible it needs space to turn.  It is also electric, which is the main reason you do not want other knife species.
 
Silver dollars are a better choice than angels here.  They need a much larger group though, I would say seven.  They attain 5-6 inches (depending upon species, there is more than one that may be seen as "silver dollar") and will eat small fish, and soft plants.  However, I would assume with the fish mentioned you will keep the light low (the BGK may well be stressed otherwise, these are generally "nocturnal" fish) which will suit the angel and others too, and the main decor should be lots of wood and branches.  Floating plants are useful here, to benefit the water quality but also shade it.
 
Geophagus jurupari would be a good fish, depending upon the tank size.  This relatively peaceful cichlid is gregarious so best in a group of 5-8, but it needs space, at least a 6 foot tank (your 125 may be this).  Leave out the silver dollars and diamond tetras, and stay with the BGK, G. jurupari, angelfish (one) and corys.  The black neons are fine as they are "left overs."
 
This could be a very lovely aquarium.

Yea I will post pics when it is finished. The tank is 6 foot by 2 foot by 21" high (oddball) I get what you are saying about the black ghost. He is actually wild caught from the rio negro and the macana zebra Knifefish is wild caught from Peru. My angel too is one of the peaceful ones... I'm pretty sure the black ghost ate the neons .
The knifes also get along they don't fight they are actually buddies. As long as I feed them right and allow them to have a log to them selves

From your first post I believe we all thought this was a question on what was planned, not what has been done.  Not much value in asking after the fact, now you have to live with whatever.  And it is very early days yet...you have not seen what may occur if the fish are normal and healthy.  Good luck.

 

[Akasha72]

Yeah, I also assumed this was a potential stocking  query not a list of already aquired fish

 

[Mattmez]

No I only have what is listed above. Plus the zebra knife
