If I have a 120 gallon tall, 48×24×24 with a FX6 canister, 50% weekly water changes. With a few caves, a good chunk of drift wood and some fake plants, would it be possible to stock it with
1 oscar
1 green terror
2 fire mouth
2-4 ctenolucius hujeta (rocket/hujeta gar)
1 stripped raph cat
1 gold nugget

I'd probably add the cichlids in last all at once, after the hujeta gar, cat and pleco grew a bit and established the tank.
 
I was confused about the tall part of the equasion. That is a standard 120.
Way too much fish. That Oscar alone is going to occupy a third of the tank .Green terrors are extremely aggressive and also get pretty good sized. Maybe if you leave them out the rest of the stock will be ok. I have no idea on the size of hujeta so if they don't get to large they may be the center piece of the tank. Two FM will either form a pair or fight or both and when breeding take over half of the tank. 4x2x2 really isnt all that big. Once you get a 12" fish in it you'll see. Id say a 120 is a good tank for 1 Oscar or if you are lucky a pair and nothing else. If it was a 180 6x2x2 maybe you could add another large fish or two if the Oscar allowed it.
 
Remove the oscar and your good. Just imo 4' is not long eniuen for a possible 15" oscar

I have a female GT in a tank that size and wouldn't put another cichlid with her as I believe she'd kill it in such a small space.

Also when all those fish are grown up its gonna take a fair chunk of water changes to keep the nitrates down. Cichlids can be very messy. :)


My personal rule of thumb for tank size is to have a tank that is minimum 4x the fish's max size in width and 8x the fish's max size in length. Obviously their are exceptions, silver dollars come to mind, a 6" silver dollar needs a tank that's longer than 4' imo.
Using that rule I wouldn't put a fish longer than 6" in your tank. :)

Any Alternatives for an oscar for the tank set up? Or will the GT be such a "terror" (haha) that I just shouldnt add anymore?
 
Id say like Kittiee Katt Kittiee Katt said gt and not much else. Anything to small will be eaten anything to big will be beaten. The cats will be ok, the gars maybe ok, the FM are probably not going to be ok.
The problem like I said before thats not that big of a tank really. Gt get 10 to 12 inches. Oscar 12 to 14 cant put them together its not going to work.

Sorry for shortening your post, just kept the bits relevant to what I have to add. :)

My GT is a female and only around 6" but still uses every inch of her tank. I'd love to get her a bigger one but finding large tanks down here is near impossible. She has plenty of room but she could definitely do with extra.


Definitely be wary of adding small fish with a GT, sometimes it works other times not so much. I had black widow tetras with my GT for months with no problems and then one day she decided she didn't like one of the tetras and killed it, I quickly took the rest of them out of her tank before more died.
The only tank mates she will ever have will be plecos/catfish I recon. :)
