Fish advice new tank

[Gourami Swami]

150 gallon? the tank will be arround 520 gallon.

When i look to some pictures on Google the hoplarchus psittacus is a really nice fish!

forgive me, I missed that line. That's why I was cautioning you about the pleco bio-load.
In a 528 gallon… go crazy I would definitely get a Psittacus, you could do an Oscar as well, many geophagus, heros. I would only avoid Mesoheros like Festae, as their aggression levels are beyond most other SA's. And crenicichla would be great, but would eat smaller fish.

I am not a fan of Oscars, to common and i don't like "fight fish"

Mesoheros Festae looks nice but are those fish really aggresive is that what you mean?

Fish that eat other fish are not an option (i am aware that all Chiclids eat small fish when you introduce them)

The Brochis Multiradius will be the smallest fish i will have and those are 3/4 inches in length but those will be save i think for most chiclids

 

[Gourami Swami]

At 3/4 inch, I think most cichlids other than geophagus would eat them. Cichlids are opportunistic by nature, and will eat anything that can fit in their mouth generally. A large hoplarchus or severum might be too lazy to catch a 3/4 inch fish, but a young growing individual would snap it up if it could. They also have spines which could lodge them in the throats of the cichlid. I would get larger ones than that if possible or grow them out a bit first. (edit- you mean 3/4 inch, or 3 or 4 inches?)
And yes the mesoheros festae are very aggressive, as are other mesoheros. I would avoid those.
Oscars are generally pretty peaceful, wouldn't call them "fight fish", some can be aggressive individuals but then again so can severums. I think one would be fine but if you don't like them then that's your call.

Have a look to the size of the Brochis Multiradius, that is a "big fish". The biggest one of the whole family

If you have "wild catch" Oscars those are much more aggresive then aquarium offspring. Most LFS have only offsrping.

But i will keep the options i mind, all the suggestions are welcome

I understand they are a large cory, I was only asking if yours are 3/4 inch (what you wrote) or 3, 4 inches. Huge difference, 3 or 4 inches would be safe like you assume, but if they are 3/4 inch mid-sized cichlids would likely snack on them. And these cats are choking hazards because of the dorsal spines.

 

[CVS1982]

Owh sorry! that is how i normally write this down in my native language

They are like 3 to 4 inches long and not 0,75 inch They are adults so big enough

And idd most fish will choke because of them!

 

[Gourami Swami]

No worries, yeah at 3-4" they should be just fine
Some other fish to look at: Acaricthys heckelii, aequidens tetramerus, chocolate cichlid

Thought I'd give a suggestion, what about Uaru?
Uaru fernandezyepezi look pretty cool and they're pretty peaceful

 

[justarn]

Yep good choices. I have;
True parrot
Wild Oscar
Uaru
Rocktail severum
I will suggest an L095 pleco I love mine

My wild Oscar is slot more chill than shop bought Oscars, looks different too. Might be a risk with even a 3" Cory if the oscar approachs 15-16", much more likely in a wild fish from the right area.

What about jaguar catfish and cichlasoma ornatum?

I give another vote for some uaru. True parrots are such a chore to keep happy and healthy IME. Unless you want stressed out livestock or be stressed out yourself about every last water param, i would choose one of the other options.
