Would this be overstocking 520 litre 5ft tank?

[taylor the beast]

Hi
Just bought a 520 litre tank 5 ft
Here’s the link ( https://www.allpondsolutions.co.uk/aquarium/fish-tanks/cabinet/520-litres/ )
And yes I have a 406 as well.
And I plan on having this as stock:
1 fire eel
1 ornate bichir
1 lima shovel nose catfish ( in UK so probably not the true Lima)
1 Oscar
1 albino Oscar
1 green terror
1 red terror
1 black nasty ( Nandopsis haitiensis)
1 rocket gar (Ctenolucius hujeta)
I have kept all of the fish except for the catfish and black nasty, so any tips would be greatly appreciated. Now I know there are 5 aggressive cichlids in a 5ft so there could always be issues but have kept terrors and Oscar for years. Or do you have any recommendations for a cichlid/cichlids combo that would/should work with the oddballs on the list? cheers.

You'll not get 2 Oscars, green terror, red terror and a black nasty to live together in a 5ft tank any how.
Your going to be well over stocked. Black nasties a lone get quite big.

Oh right yeh that’s quite big actually yeh your right I was thinking they were more like jack dempsy size, what would you have in there as your centre piece cichlid/s

Agree with Andy, in a 150 gal I would think maybe one or two of the species you suggested would max it out.

Yeh okay agreed,
So maybe
Albino Oscar
And red terror? What would you have, if it was your tank?

Sex depending, but if your wanting males, a green terror might live with one of the non cichlids but any of the big cichlids I would be looking at keeping it solo.

Yeh have been thinking about that, your probably right

Agree with the others, maybe one cichlid, or the 2 oscars, a pair of one species, with the non-cichlids.
This about all that tank will hold comfortably as adults (or even semi-adults).
If you grew a couple cichlid species in it together from juvies, there is a chance that theymay divide up the limited territory, but not the haitiensus.
I kept my pair in a slightly larger tank, and they wouldn't accept any tank mates, cichlids or non-cichlids.

Yeh sounds best to be honest, yeh I’ll remove the nasty till I get a bigger tank, so I’m thinking maybe green terror and 1 Oscar, I have 2 55 gal and 1 75 gal spare so if I need to remove the Oscar or terror at some point then that won’t be a problem. I was also thinking that I’ll have the non cichlids in there first then get the Oscar and terror at the same time same size. Thanks for your help
