Apisto help for 20 long

[Roko]

Hi all, I am first time on this forum. I had problems with login and signing but finally I made it.

So i have 22gallon long tank 85 liter 80x30x35cm. I have school of harlequin rasboras, school of panda corys and few ottos. Latest introduction was male cacatuoides he was just 2cm long when I added him and there wasn't any sign of aggression now he is I think almost fully grown.
I was thinking to add another apisto but I am not sure should I add 1-2females (I am at fear that cory would get beat up when spawning comes, and I don't look on breeding them) or let say 1 male baby agassizii and what would work the best.?

So can you suggest me what to do from experience option 1, 2 or just leave it as it is.
Also I should mention that tank is very planted and I do 50% wc weekly also there is alot of hardscape.

By now your cac male probably considers the entire tank his territory. I wouldn't add female cacs unless you want to breed them. If you do, you will need to remove any bottom-dwelling fish (corys) just to be on the safe side. If you want to add another apisto I would suggest a species with a different body shape and finnage. Also the new fish needs to be about the same size as your present male. Otherwise I see a dominance problem. Either way you will need to remove the male cac temporarily and re-arrange the aquarium decor. This will allow the new fish an equal chance at establishing its own territory.

Tnx on answering. So as I thought it isn't that simple to introduce another dwarf cichlid, I don't have space for breeding them so females aren't a option.
If I introduce smaal 2-3cm male you think he would get attacked by older. I don't have good LFS in area so I will try to find one or I will wait until I can get let's say bolivian ram.

Or I will just leave tank as it is, I even have colony of blue rili shrimps that my cocato don't bother.

A Bolivian Ram or Laetacara spp. would be a better option. Without knowing the numbers of fish in your schools, I can't suggest what to do. Of course: If it ain't broke, don't fix it." Or as my family tells me all the time: "Don't touch it, you'll break it!"

I have 8 harlequin rasboras, 6 panda corys, 4 ottos and one apisto and some blue rili shrimps. Lots of slow and fast growing plants, fluval 206 and one hang on back filter that is more like skimmer/polisher for water and I do 50% wc weekly that's it I think. Yea I like bolivian ram alot but in my country I can only find variety of German rams and my temperature would be good for them.
